cock block

One who spoils a close friends attempts in mating

1. When Bonni foils finnys plans by calling up finnys girl. Thats true cock blocking!
2. Bonni, Joby, Sunil and Sajan goin over to Bino's house When Bino and his special someone are at the house trying to get it on; thereby stopping any chance of getting any that night!.
That is referred to as tag team or Group Cockblocking
