No mayo tuna fish 

Describes the odor coming from a person's unclean private parts (either gender).

At the gym today, I changed my mind about riding the excercise bike because the odor coming from the seat smelled like 'no mayo tuna fish'!

Extra No Mayo 

As you are finishing up intercourse or masturbating, instead of cumming inside or on the girl, or in your hand, you get up and walk over to the nearest trash can and proceed to ejaculate into the trash.

"Yes, Lemme get a number one combo with Extra No Mayo" the customer asks. The underpaid fast food employee sighs and rips off his pants, proceeding to furiously jerk off while aiming at the trash can.
