cumsniffer 

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.

Bumsniffer

If you are really promising yourself not to swear/curse; the word Bumsniffer comes out of your mouth.

Also, if you have noticed sniffing bums really isn't pleasent. So People will also take it in as a hurtful response. Just like fuckyou, or bitchplease. IT's all the same. Bumsniffe is just the nicest form to put it in :)

You can also say it randomly. Try it, It's fun.

"YOU FU..BUMSNIFFER!"

Person 1 : "Hey ______, you look like a douche today"
Person 2 : "Shut up Bumsniffer"

Random Person 1 : "....Bumsniffer"
