waxy hairy deep cave dwelling gob of lard like substance reeking of wet band aids and buffalo sauce. Often found stewing in the pungent oniony smelling naval cavities of the obese species.
one day upon exiting the shower, I observed a large gob of hairey button butter crawling its way out of my boyfriends cavernous belly button, he then proceeded to fling sling and sniff. smells like wet band aids and burnt vinegar.
Butten (or buttening) is the art of pushing someone elses nose upwards to make them look like a pig while they grin and bare their teeth.
Can be used in good or bad situations.
