A bromance is a very close and non-sexual relationship between two or more men. It is an exceptionally tight, affectional, homosocial male bonding relationship exceeding that of usual friendship, and is distinguished from normal friendship by a particularly high level of emotional intimacy. The emergence of the concept since the beginning of the 21st century has been seen as reflecting a change in societal perception and interest in the theme, with an increasing openness of Western society in the 21st century to reconsider gender, sexuality, and exclusivity constraints.

Fuck is a profane English-language word. It often refers to the act of sexual intercourse, but is also commonly used as an intensifier or to convey disdain. While its origin is obscure, it is usually considered to be first attested to around AD 1475. In modern usage, the term fuck and its derivatives are used as a noun, a verb, an adjective, an interjection or an adverb. There are many common phrases that employ the word as well as compounds that incorporate it, such as motherfucker, fuckwit, fuckup, fucknut and fuck off.

Gaydar is a colloquialism referring to the intuitive ability of a person to assess others' sexual orientations as homosexual, bisexual or heterosexual.

The word geek is a slang term originally used to describe eccentric or non-mainstream people; in current use, the word typically connotes an expert or enthusiast obsessed with a hobby or intellectual pursuit. In the past, it had a generally pejorative meaning of a "peculiar person, especially one who is perceived to be overly intellectual, unfashionable, boring, or socially awkward". In the 21st century, it was reclaimed and used by many people, especially members of some fandom, as a positive term.

Hella is an American slang term that originated in Oakland, California but has since spread to become native slang to all of the San Francisco Bay Area. It is used as an adverb such as in "hella bad" or "hella good" and was eventually added to the Oxford English Dictionary in 2002. It is possibly a contraction of the phrase "hell of a" or "hell of a lot [of]", in turn reduced to "hell of", though some scholars doubt this etymology since its grammatical usage does not align with those phrases. It often appears in place of the words "really", "a lot", "totally", "very", and in some cases, "yes". Whereas hell of a is generally used with a noun, according to linguist Pamela Munro, hella is primarily used to modify an adjective such as "good".

"Lipstick lesbian" is slang for a lesbian who exhibits a greater amount of feminine gender attributes, such as wearing make-up, dresses or skirts, and having other characteristics associated with feminine women.

LOL, or lol, is an initialism for laughing out loud and a popular element of Internet slang. It was first used almost exclusively on Usenet, but has since become widespread in other forms of computer-mediated communication and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO and ROFL or ROTFL. Other unrelated expansions include the now mostly obsolete "lots of luck" or "lots of love" used in letter-writing.

Mom jeans is an outdated slang term for high-waisted women's jeans that were originally fashionable in the late 1980s and early 1990s. In the late 1990s and 2000s they were mainly worn by middle-aged American women and considered unhip by trendy younger women.

A muffin top is a slang term typically used to describe a person's body fat that extends horizontally over the edges of the waistline of tightly fitting pants or skirts, visible when there is a gap between the upper and lower garment.
