I was down to my last 20 dollars in the slot machine and then I went on a heater. I was on a heater last night at the craps table, I made a lot of money!

A firearm- Usually a handgun or revolver. This term came from the 30's mafia/gangster times. When continually fired, the barrel would get very warm- hence the name heater.

I believe in common usage that heater is a term now applied to all firearms, not only fully automatic firearms.
