Oh Sheet 

This phrase is most often said first thing in the morning after waking and realising a really stupid thing that you did the night before. Usually the stupid thing has occurred as a result of one too many double vodka redbulls. Oh the embarrassment!

"Oh Sheet there is a dude with a beard in my bed!"

Oh sheet! I cracked my phone’s screen!! 🤯
