Any stupid/retarded/stereo-typical reasons that a woman will not have sex with a bf/ husband. Its basically a blockage of their vagina hence a cock block. For the boyfriend after being together for at least 3 and a half months and having oral with each other, saying that you are "not ready" to have sex is one of the most common cock-blocks and is inexecusable. For the Husband, saying that you are not in the mood is also unexceptable. If you have a baby within the last year or are pregnant those do not meet the requirements to be called a cock-block. The woman being on her period is the one acceptable excuse and does not qualify as a cock-block
" Man me and my girl have been together have been together for 6 months and we still havent had sex yet!"
"Damn dude, thats a real cock-block she's putting up there."

"It's been a year since me and Charlotte had Timmy and she still doesn't want to have sex....Fuck her stupid cock-blocks"

2.) I realized that my exit was coming up so I began to change lanes, but that ricer cock-blocked me

3.) The traffic on the highway was hell, mostly because of that soccer mom driving the minivan in the far left lane, pacing and matching speeds with the semi in the middle lane. She cock-blocked us all.
