The term used in the gay community to describe a boy or man (often teenage or young adult) who dresses up as a girl, frequently appearing in public or posting online pictures of themselves dressed as a female.

Unlike real transsexuals, and unlike drag queens, buffalos do not dress up for comic effect or from real belief they should be a girl. The exact reason varies with the person, but it tends to be from a mistaken belief that to be beautiful one must emulate "classical beauty", i.e. femininity.

Buffalos therefore often have deep self-image issues which manifest as dressing as something "beautiful", often coupled with a facade of overconfidence or swagger. Buffalos crave the attention given to their new "beautiful" appearance.

The term "buffalo"is derived from "Buffalo Bill", the tortured character in the movie "The Silence of the Lambs" who famously dresses up as a woman while saying "would you do me? I'd do me".

Buffalo is a drinking game. That can get you fucked up in a matter of time. If you aren’t careful.
It’s easy! You just drink from your non-dominant hand. If you do drink from it. You have to kill what ever you are drinking.

Example: I’m right handed so I would drink with my left. If I were caught drinking with my right hand . You would yell “Buffalo” at me. Then I would have to shotgun the rest of my drink. If you get buffaloed and you are drinking with the correct hand. The buffaloer has to shotgun their drink.
