Get the debonifier mug.
A term invented by the citizens of Aberystwyth to describe a sensation leading to the penis becoming flacid. Normally used to get out of tricky situations with the girl, normally times where speed and appropriateness are an issue.
Thinking of an asian going "aowwwww" debonified me and I was safe from my physics teacher.

I was debonified when I saw that fat chick sauntering down the street.

When that chick put a microphone up my ass I really felt debonified.
