When you spray an insanely large amount of air freshener/cologne/perfume/etc. to be rid of some scent whether it be good or not.
Usually results in so much of the new scent that you must commit aromacide again just to even it out. Sometimes this becomes a never-ending cycle until one person runs out of what ever shit they are spraying.
Boy 1: Dude, I was smoking in your bathroom last night.
Boy 2: Don't worry, I commited aromacide in there as soon as you left.
Mom: Wtf happened to all our Febreeze?

Boy 1: *farts*
Boy 2: JESUS CHRIST, DUDE, I HAVE A DATE TONIGHT!
Boy 1: Here's some Axe, go commit some aromacide and she'll never smell a scent a' me or my lunch.
