Get the isamug. Short for international super assassin, ISA describes any man or woman who kills others for a living, yet has not quite attained full ninja status due to the use of large BA weapons such as rocket launchers and non-suppressed light machine guns. An ISA enjoys making his or her presence known.
Jeff: Dude, Arnold Schwarzenegger is totally an ISA.
Kelly: You know he's just acting, right?
Jeff: No he's not. He couldn't have become governor without being an ISA.

Get the isamug. Contraction of "inshallah" or "insha Allah", literally "if God wills" or "God willing." A phrase Muslims are supposed to use whenever expressing an intention or prediction of the future, as a reminder that God is all-powerful and all human intentions are subject to His will. In practice, though, this pious thought is often used to evade personal responsibility, and when indicating an intention in conversation the actual meaning can vary all the way from "only an act of God will stop me" to "I actually have no intention of helping you/keeping this appointment/etc. and will have a stock excuse prepared if you call me on my flaking out."
"I'll be totally screwed if my computer's not working on Monday. Are you sure you can fix it by then?"
"ISA."
(privately) "Oh fuck."
