Dyke: a word used to refer to lesbians; a term that lesbians use in gay circles; originally a derogatory term for lesbians, now often used with pride.
Frumpy: A
female with lack of concern for appearance; clothing style that usually consists of bagging; careless slothing; no style; considerably out of shape.
So, a ''frumpy
dyke'' is ''a lesbian with lack of concern for appearance, from clothes to body shape''.
'I would consider myself a
feminist, and I didn't even know that at the

dyke'.
