SUI 

'Scooting Under the Influence'

To be caught riding your scooter (a Macro scooter, if you will) whilst under the influence of alcohol. Scientific inquests have shown that enjoyment levels augment by at least 150% whilst scooting under the influence, whilst death rates rise accordingly.

The most famous recipient of an SUI is the ficticious John "J.D" Dorian, from Scrubs.
