Boston Cock Block

Unlike a cock block, when anyone can jump the gun on you. When you're scouting a girl at a bar and your bro jumps in front of you to kick it.

Mike to Phil -"You see that hottie in the blue tank top over there by the bar? After I take a piss I'm on it."

**Mike goes to the bathroom and comes back to find his buddy Phil all over Jenna in the blue tank top**

Justin to Mike - "Oh man did you see that? Phil just layed a Boston Cock Block on you. Harsh!"

Urban Dictionary Block

Noun: this is the sad condition during which you think of a slang term, the meaning of which escapes you, but you are riding in the car, lost in space, or engaged in a sexual act, and therefore can't access a computer... by the time you are at said computer, the term has fled from your feeble memory.

as in " I wonder what the hell "roflcopter" means... when I get to work, I'll UD it..." 5 minutes later... "Dammit, I have Urban Dictionary Block... WHAT THE HELL WAS I GOING TO LOOK UP?!?!?!?!?"
