Slatherfest

To slather Jif peanut butter all over one's body for sexual purposes. This can be done with a partner, in a group, or even by one's self. One can try this with Skippy or the generic brand, but the taste and consistency of Jif far surpasses these cheap substitutes. It has the unique ability to be able to go into cracks and crevices much better. A nice glass of cold milk should always be on hand when "Slatherfesting"
Slatherfests can get quite out of hand, The Valentine's Day Slatherfest of 2007 resulted in 12 hospitalizations.

"What did you do last night?"
"Dude, it was a slatherfest, I'll probably have Jif dingleberry for a week
