The act of forcing air out of the tip of a fully erect or half erect penis. This is basically the male form of queefing.
I woke up this morning with morning wood and I accidentally peefed my bed. It startled me so much that I shit the bed. What a morning.

A portmanteau of penis and boof. To understand the joys of the peef one must be familiar with the second most noble way to take a drug: the boof.

Once you have read up on the art of boofing, apply that knowledge to your penis. That my friend, is the peef.
My ass was too sore from boofing all that kratom last night so today I opted to peef it instead.
