In a sexual context : it involves inserting a (pealed) banana into a girls rectum prior to engaging in anal sex. Afterwards, a bowl is used to catch the result, a lukewarm mixture of jiz, mushed banana and excrement.
Doing a Banana split is quite popular in latin-american countries. A friend of mine did one in Cuba the other day.

Slang for anal sex, especially when the penis is thrust hard and unexpectedly causing an abrupt opening of the anus.
Damn look at the hiney on her, I'd like to split her ass.
Lisa is walking funny, Matt must have been splitting ass last night.

The potatobug is a sexual position where the woman's legs are completely bent back and up over her head, making her look like a rolled up potatobug while the guy has sex with her from the front, leaning on the back her extended legs.
