A terrible situation. A horrible inconvenience. The worst thing imaginable. Nightmare of a situation. When speaking this word, it's usually referred to in secrecy or while acting like a valley girl or speaking to a best friend.
After I walked into the bar and saw my ex with his new girlfriend, I knew the whole night was going to be total terrids, and it like totally was.
A combination of terrible and horrid.
“This is terrid.” “I just did the business exam.. it was terrid.”
