RUI 

Riding Under the Influence. When you are "operating" a bicycle/ scooter/ skateboard while on drugs or alcohol. This is actually illegal in many US states.

I tried to avoid drinking and driving by riding a bicycle to the bar, but then I got busted for RUI by this asshole cop.

Rui 

A very nice person, very likable, VERY underrated. You should be friends with someone named Rui. they typically don't say it but they want you to let them know they are needed.

Hey Rui! You are my best friend because you are unlike all of these fake whores.
