Like an orgasm for the nose. When someone smells so good it makes you want to say GOD DAMN.

A smell referred to as a smellgasm usually means that an object's smell effects your nose clit and gives you an amazing orgy in your nostrils, for first timers it may pop their nose cherry, may cause bloody nose.
