look up any word, like sex:
1.An all-out quelling of one's attempt to talk to a lady friend, dealt by an extreme faggot that usually iniates the block with a swift punch to the scrotum. This exceeds the level of a cockblock.

2.A bit of hardened residue left in a douchebag's drainage valve that allows the vaginal excriment to form to or more streams as it slops out.
"Yeah I was making a good conversation with a stocked babe, and then JB runs up out of jealousy and hammers my nutsack. Such a douche block.

*With an educated english accent: "Oy! There seems to be a douche blockage seperating the excriment into these assorted bowls."
