A verb, as in "to Black Knight".
Refers to the act of attacking an opponents legs with one's teeth.
A phrase coined by Max Brooks, in his work World War Z, and itself a homage to Monty Python and the Holy Grail.
Black Knight: All right; we'll call it a draw.
Arthur: Come, Patsy.
Black Knight: Oh, oh, I see, running away then. You yellow bastard! Come back here and take what's coming to you. I'll bite your legs off!
