A player in an online multilayer game who uses C4 or other explosives to repeatedly mine a spawn point and detonate it as soon as players spawn. This is seen by many as being a way for people with little skill playing a game to get a high kill count. It is seen as "whoring" because it takes no skill to do, yet you get rewarded for it.
Not all players who mine spawn points with explosives are C4 whores. A C4 whore uses spawn point mining as their primary method of getting kills and avoids trying to kill other players with their other weapons. They will often do it to the point where large numbers of players will leave the server in disgust.
Some game servers, to combat this, make ammo crates not give out C4. The result is that a player only has the C4 that they spawn with. Limiting the damage a C4 whore can do.
Dude, quit being a C4 whore and let me spawn.
He's being a C4 whore. Killing all of us before we can even move. Someone kill them so we can actually play.
Don't play on that server. Too many talentless C4 whores.
C4 whores will be banned.
