gitsurfing 

Gitsurfing (aka biddysurfing) is when a young person (usually around 9-15) runs up behind an old person and jumps on his or her back, the momentum of the run-up causing the oldie to move forward a few steps before falling to the floor. The craze, though possibly not the words gitsurfing or biddysurfing, is thought to have originated in Manchester in the mid-1990s and appears to be slowly growing in popularity.

I'll give you a thick ear if I hear you've been gitsurfing again.

Repressed gay issues.

When a man offers free blowjobs at gay clubs, yet claims to be "100% straight", he clearly has gissues.
