look up any word, like tribbing:
FRUNDAY = Friday, Saturday and Sunday,

Basically the weekend said in a different way.
Sian: "Did you have a good Frunday?"
Joe: "Yes, it was fabulous babes."

A Friday that feels like a Monday.
Guy: God this feels like such a Frunday!
Girl: Yeah but at least it's the weekend tomorrow.

When Friday feels like a Sunday due to too many cheap drinks on Thirsty Thursdays & Struggle Town hits before the weekend has even started.
Sally: I keep thinking it's Sunday! We usually feel like this at the end of the weekend...
Beryl: Nah, it's Frunday! We still have the whole weekend ahead of us!!
