Acronym for "Thank Universe it's Friday". Can also be used as an acronym for "Thank You it's Friday". Used to compliment God (Universe) or any person (You) for the occasion of the weekend that everybody can enjoy off from work or school.
"TUIF", I can't wait for the weekend.

"TUIF" tomorrow!

During the business meeting on Friday I shouted "TUIF".

I can't believe my Boss came in late on Friday and made us stay longer on a "TUIF".
