When a male gets an erection and attaches a needle to the end of his penis either by tape or some type of paste and uses it as a 'stinger' to ward off unwanted sexual advances. The plural is called a hornets nest which is when a group of men get together in the name of sport and literally have cock fights. The first hornet stinger to draw blood is the winner.
While i was bent over picking up my towel after a shower wes came rushing up behind me naked. I quickly turned and gave him the hornet.
