YesterFriday
When you've had more than your fair share of cocktails on a Saturday night and into Sunday morning. You're trying to articulate a story about something that happened on Friday and mid-sentence, you realize that since it's now Sunday, Friday isn't yesterday. You then try to be cool by blending Yesterday and Friday.
Thanks for filling my glass of wine for the 10th time. That reminds me about a delicious Malbec that I had yester...uh Friday...YesterFriday.
