Going Butt Fuck 

When someone becomes extremely excited or stimulated as if they had a severe form of A.D.D. Much like Going Ape Shit, but usually in a more positive way. Similar to a fangasm.

Joe Bob McHootenanny: "I was in the mall the other day and I didn't want to get anything I didn't need. Then a lady by the toy store offered me a huge figure of the Big Daddy from Bioshock that was so well sculpted and painted it looked real! I proceeded to start going butt fuck and payed the $245 it cost... And that's why we can't afford to pay the rent this month, honey."
