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.
"HAR HAR HAR!"
Well someone has Knockback Laughter...
