I am getting c-blocked from all angles...either my girlfriend gets a phone call or someone comes to her house right when we are ready or I'm on line chatting with some hot babe and my computer crashes.
You are at a bar talking to a girl and your friend jumps between the two of you and starts talking to her.
Girls can C-Block guys too by preventing them from getting in their girlfriend pants. Usually by making them leave with them instead of you.
