The act of flatulating under your covers, waiting 10 seconds, then sticking your head in and sniffing it.

Often confused with Dutch Oven, but the difference is, with dutch ovens you're doing it someone else. With Nazi Incinerator, you're doing it to yourself.
Friend 1 - "You know what I love."

Friend 2 - "What?"

F1 - "Sitting in my bed Nazi Incinerator'ing myself."

F2 - "What's that?"

F1 - "Rippin' ass under your covers, then sticking your head under it to smell your gas in all it's glory."
