Lumpy Peanut Butter 

Accomplishing a Lumpy Peanut Butter is no walk in the park. Many have failed resulting in massive injury. The first step in completing this amazing feat requires courage. First, the male (or shemale) will stick is entire scrotum into an inhabitted wasps nest and rapidly shake and thrash about as if the person was having a seizure. Next, the person will submerge their now lumpy sack into a jar of skippies peanut butter. Finally, the person will hang closely infront of a pack of starving wolves and wave their now perfectly prepaired testicles in a taunting manner. They will ultimately be torn to shreds resulting in the greatest high of all time, otherwise known a s a super high.

Andy- Hey man i just did a Lumpy Peanut Butter!
Josh- Wow really?! How was it?
Andy- FUCKING AWESOME!!!

The Peanut Butter Cup 

When having anal sex with a fat chick, you pull your dick out and you fill her belly button with the shit stuck to your dick.

So I'm slammin it in her soupbean and I consider going for the pink sock, but since I work for her dad, I decided to just give her The Peanut Butter Cup instead.

the peanut butter effect 

A lingering smell.

HISTORY
When one eats peanut butter the smell of peanut butter sticks with them for a extended period of time even though all evidence of the peanut butter is gone.

Often related to other items of similar consistancy. (read:feces)

Example 1:
A dog does his business outside and comes in to sit beside you. The dog smells very much like his dirty business even though his anus is completely free from 'cling-ons'. This is the peanut butter effect.

Example 2:
One is doing laundry and notes the 'peanut butter effect' on a pair of underwear. The underwear may only inhibit a foul smell or may be accompanied by 'skid-marks' after being well used.

I.Q. of a peanut butter sandwich 

Perhaps the most famous and most recognized Tomism (see "Tomism"), the term is used as a general insult. Tom K. would speak of another person as having "the I.Q. of a peanut butter sandwich". It is believed that Tom did not originate the phrase, however. In recent times, the phrase has been combined with "without the jelly" on the end- supposedly to indicate that a peanut butter sandwich WITH jelly has somehow a measurably higher I.Q. Go figure.

"Frank is such an idiot. He's got the I.Q. of a peanut butter sandwich."
