look up any word, like tribbing:
 
1.
an overtly/stereotypically masculine or masculine-acting woman. can be used to denote an individual, or the dominant role in a lesbian relationship.
marge is pretty butch. she's really strong, fixes cars better than a mechanic, and takes damn good care of her woman.

2.
A (traditionally) masculine man or woman, and especially a masculine lesbian. Often the "dominant" partner in a lesbian relationship, and especially of a butch/femme lesbian relationship.

Dressing masculinely does not make a woman into a lesbian, contrary to popular belief; it's usually more convenient.

Acting masculinely only means that's the gender role that the person identifies with; it has nothing to do with their sexual life. A highly masculine man could be gay for all we know and a very feminine man could be straight for all we know, and both of these cases are frequent.
Long, frilly dresses? Hair swept into a bun? Makeup? Silks and satins? Sweet, shy disposition? Definitely a femme.

Short hair? Denim? Leather jacket? Nose piercings? Motorcycles? Suits and ties? Loud and aggressive? How could that be more butch?

5.
Basically a character from Pokemon. His partner is Cassidy. Cassidy and Him are a part of team rocket, so that makes them clash with Jessie and James sometimes. Butch is famous for having his name mispronounced.

He was one of funniest in Pokemon. I will never forget him.
Ash, Tracey and Co.: Its Cassidy and Biff!

Butch: HEY ITS BUTCH! NOT BIFF!

Jessie and James: Oh, its Cassidy and Bill.

Butch: ITS BUTCH! NOT BILL!

Random person: Its Cassidy and Butch!

Butch: ITS BUTCH NOT--Oh wait.
