Keester Kiss 

An imprint left on bedsheets as a result of the failure to sufficiently wipe your ass before sitting on a bed naked.

It was evident that Bill forgot to wipe as seen by the keester kiss left on the sheets.

Kneeback

knee bangers 

When a lady gets so old that her breasts sag all the way down to her knees, they then stop being breasts as such and become "knee bangers". Another tell tale sign is when you shout, "Show us your tits!", they must lift their skirt in order to do so.

(Can also be spelt as one word - "kneebangers")

"Those knee bangers make her look like she has four arms!"
"Yeah you're happy know because they're big and firm, just wait until your older... when she turns sharply, you'll get some knee bangers to the face..."
