odorgasm 

Getting off to a pleasant aroma.

I enjoy nice smells as much as anyone, but I don't recall ever actually getting an odorgasm over any of them.

oorgasm 

Having multiple orgasms. It's like a regular orgasm but with more than one O.

After the second climax, Denise thanked Jack for the oorgasms.

Odourgasm 

The enjoyment felt after letting off a particularly large smell, usually in the form of a fart or shit.

Despite being greatly enjoyed by the creator of the smell, the smells are usually hated by those around.

John let off a huge fart earlier, everyone was gagging but he was having an odourgasm!
