Preemptive cock-block

The act of preventing interaction between one or more females with one or more men prior to any communication between the two groups, thereby negating the need to cock-block them later on, after they have started making moves on the women.

A: Hey man, how were those girls that Johnny showed up with?
B: I don't know, he sat down at a different table, so I couldn't talk to any of them.
A: Ah, dude, that was like a preemptive cock-block.
