butter boner

When a man has a full erection, but it still isn't quite rock-hard.
Firm, yet squishy.

ex: He tried to put it in my butt, except he has a butter boner so it didn't penetrate.

Semen, male ejaculate.

Dude I put my boner butter on her bread, and by bread I mean face, and by boner butter I mean jizz.

boner buster

To lose an erection, ruin a potential sexual opportunity or potentially happy moment.

Guy 1: My girl was about to give me oral by the fire when her roommate came home.
Guy 2: Did she keep going? Did the roommate join in?
Guy 1: NO! She was embarrassed and asked me to leave.
Guy 2: What a boner buster!
