A person who enjoys, and takes the pride and joy in making a man or transvestite ejaculate, and proceeds to smell the produced semen, or going as far as inserting the semen into the nostrils.
Sunny broke into my house last night and cumsniffed the dried semen residue on my used condoms in the trash.

This guy is a fucking cumsniffer, don't trust him in your house...he'll sniff all your cum up.
