When one person sticks an aluminum tube up another person'd Butt and pour grape jelly, orange Fanta and petroleum jelly down the tube, then you connect the tube to your Butt and your friends butt, vigorously twerking until the tube until the tube disappears which then is followed by a loud cry of SPUGGLE BUTT!!
A guy who may look like an intimidating strong hottie on the outside. Very macho, but on the inside he is a giggly lil kiddy all full of lovey doveys, usually only a girlfriend can see this special side of him.
"That guy seems so serious!" "No way, we've been dating for over a year now, he's the biggest snugglebutt you'll ever meet."
