The intimate act of attaching a peeled banana to the male’s cock and having his partner chew it up into a mush, and then surrounding the cock in it. The couple then proceeds to have sex in any position they prefer with the mush then spreading out inside of the woman’s vagina.
Woman: “We had some amazing bananas yesterday night, they tasted amazing on my husband’s cock, and had great texture for my insides. Best banana split delight ever.”
A popular act in sex shows around the world. Particularly the Red Light District in Amsterdam. A woman peels a banana and inserts it inside her vagina and audience members are selected to eat it out of her. ( This is something I witnessed with my own eyes not folklore or urban legend or what I heard from some guy)
“We’re going to the red light district to watch a Bananashow”
Sales team lingo when the when selling a known-to-be inferior product (a banana) to a stupid or unwitting purchaser (the ketchup). Often members of the sales team will find reasons to repeat the words "banana ketchup" in front of the purchaser to openly mock their stupidity.
