When performing 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.
