A rare disease that only goes to the sweaty try-hards, trying to get a laugh and not a fake one. This disease will make you knock your head back and laugh up to the ceiling. This laugh is very easy to pick out of the crowd when you hear it. When you hear a har-har-har sound, you will feel bad for someone.

knockback is a chunk of semen that gets stuck in the male penis shaft as he attempts to ejaculate causing it to build up pressure until it is released as a massive chunky was of semen.
Jemima: Last week I was giving Chad a gobby and his knob started pulsating but nothing was coming out and then all of a sudden his knob stopped pulsating and a massive wad of knockback just blasted out of his cock and hit the back of my throat and I was choking on it for a good 15 minutes.
Cindy: oh no that sounds horrible, I hope I never have to experience knockback like that.
