n. a very large (rotund), tall, or manly, lesbian-looking female.

perfectly described by Ellen Albertini Dow as Grandma Mary Cleary in the movie 'Wedding Crashers' (2005):
"But that wife of his, Eleanore... BIG BYKE, HUGE DYKE, UGLY RUGMUNCHER, BIG LESBIAN MULE!"

associated with a deep voice, occasionally a masculine style of dressing, and a tendency to grunt or roar.
"WHOA, Sofia look at that girl! She's deffinitly a dyke."
