pocket healer
The guy/gal following you in PvP (in MMOs), healing you. Basically, your personal healer. Sadly, they're the first ones to be attacked if the enemies are smart. If they're not, they get owned. Be nice to pocket healers... or you'll die.
Me: Yo man, I'm dying here! Throw a heal plz!
Pocket healer: *heals me*
Me: Thanks! Sup, bitches? *proceeds to destroy enemies*
