bow-leggacy

When someone does something great, amazing, or totally rad, but thru clumsy retarded dumb-assed means.

Man, that's forever going to be George's bow-leggacy, he backed off that ladder and ended up saving all those old people from that fire because he cracked his head on that pile of old books which set off a chain reaction of events that lead to putting out the fire.
