"GRAAAAH! HAM DOCTOR!" Marcus shouted when he stubbed his toe. Mothers around him covered their children's ears; they didn't want their kids to hear this soon-to-be vulgarism.
In gaming, an extremely derogatory expression describing a stronger, more skilled player who follows and protects weaker players while they play the game.
The phrase references the common knowledge of fat kids getting out first in dodgeball- the noobs are the fat kids of the game, or the "hams".
"Fuck! I almost had that kid until his teammate hit me with a headshot!"
"Tell me about it, man. What kind of sick fucker hits level 50 just to be a Ham Doctor?"
Obscenely crude and sexual, it is the act in which a man or woman stuffs a woman's vagina with so much clove it'll make her look pregnant -- (Clove being one of the main ingredients in seasoning ham). After she can no longer contain anymore clove the man or woman plays doctor and delivers the clove baby. Thus making him or her the Ham Doctor.
