The Butterbutt, or, more properly, the Yellow-rumped Warbler (Dendroica coronata) is one of the most common warblers in North America. In summers, males have streaked backs of black on slate blue, white wing patches, a streaked breast, and conspicuous yellow patches on the crown, flank, and rump.
I saw a butterbutt flitting around in the tree outside my window

Although it may be used to describe an unattractive butt, it can also describe an extremely attractive butt.

To slather some butter onto a persons gluteus maximus. This usually occurs if a person runs out of lubricant. (Do not attempt in your household or anywhere for that matter)
"Babe! Where's the lube!"
"I can't find it!"
"Fine then just get the butter butterbutt;)"
