Nasty Sydney

When a man squirts mayonnaise up his significant other's asshole. The person with the mayonnaise up their ass then farts as hard as they can with the intention of spraying the mayo into their partner's mouth

Damn that bitch willing to do anything. She even let me pull a Nasty Sydney!

When one nasties, they made a mess out of a situation. Similarly to Chucked Up, when one nastied a situation, they made everything awkward, or just uncomfortable for everybody involved. Can also be in athletic events when one makes a mistake.

Person 2: Sure
Person 1: I'ma stand next to you and not dance with you even though I just asked you to dance.
Person 2: Ok I'ma leave.
Person 3: You nastied that up Chuck
