When you're trying to speed on the highway and some asshole blocks your lane driving at or under the speed limit when they don't have to. Especially frustrating when the road is completely traffic free except for the guy ahead of you
Driver: Fuck!

Passenger: What?

Driver: I'm trying to get to class on time but this mook just cut me off going way too slow

Passenger: You just got car cock blocked

Driver: Feels bad man

Get the Car cock blocked mug.
when someone offers a girl a ride home in an overcrowded car with the intention of preventing consensual sex
the night was over and everyone was leaving and then miraculously she was offered a ride home in a 4 seater with 7 passengers by a master at the clown car cock block
