Stomp

From QWiki

Stomping someone deals 10 damage to the opponent and 5 to yourself. It works by jumping and landing on your opponent from such a distance that falldamage would be applied. It's not common but a fun technique to humiliate your enemies. Works in KTpro and KTX so you can do it on any QuakeWorld server
