Getting drunk, then high, then awesomely stupid for a period of indeterminable length, but generally must last at least an evening plus all night and some of the morning. Mash-up heads will take anything to increase the length of time to talk nonsense. Evening ends with possible bed wetting episode or discussion about love/drugs/energy/music. Pizza is often ordered the next day.
-Me gonna get mmmmmmmmmmmash-up.

-"Is that Tom over there fucking up his mixes, he sure is a shit deejay."
"Cut him some slack, he is mash-up."

-Look, its my day off tomorrow and I wanna get totally mash-up.

-"Mash up, get me crack up, on the rack up, shut up and smack up, on a track up" Apocryphal song attributed to someone who is mash-up creating a new and awesome track.

-You look mash-up.

-Mum, I got fuckin mash up last night.
