oral sex on a man, one punches
him in the testicles just before
orgasm. The surprise pain replaces
any pleasant feelings
received from the orgasm, or stops it altogether. Can be used
as a punishment or as a sexual act.
If two gay males are involved, and it is being used
as a punishment, the term then becomes 'Sucker punch, gay revenge'. However, it is performed in the same way as mentioned above.
