Originally used as a birthday that does not go very well, later bastardized into any unfortunate happenstance
Birthday Boy: Oh a surprise party? Awesome! thanks guys! ....Wait a minute...there are only 2 balloons? that's it, I'm leaving...SAD BIRTHDAY!
Jazzy: Man, It's 3 AM and I still have a lot of homework to do...I guess I have to pull an all-nighter...
