Oblivious cock
A dad who doesn't know he's stopping his kid from getting laid because he's at home and thinks he's being cool by watching TV
My dad was watching TV and didn't know I was trying to get laid. He ruined everything.
My mom was home watching a show and I had to make out with my girlfriend in the garage.
My dad didn't know he was cockblocking me by being home. I had to sneak out to the park.
