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!"
