PB & A

Peanut butter & Anus Is an act when one partner has jelly (their choice of flavor) inserted into the anus with a turkey baster and then peanut butter is spread over the ass. As the other parter is consuming the peanut butter the jelly is ejected.

While performing the PB & A both partners can get quite messy.

PB

Personal Bowl, When one has the urge to smoke without the urge to share. Usually smaller in size but can vary depending on how blitzed you plan on being.

2. I got enough weed to get me high nigga I can't smoke you up imma just load me a PB.
