A variant of the "rusty trombone", this is where, after taking several kinds of laxitives, a man asks his partner for a rusty trombone. One they have assumed the position, with their mouth right in front of the man's cornhole, he drops a stinky duece right in their face (mouth, if possible) and yells "SURPRISE!"
Becky wasn't expecting it, but Carl gave her the worst shit surprise i've seen since Arnold got elected governer.
