Sleepsitting

The act of staying up all night to wake up a friend early in the morning. This usually results in fucking up your own sleep schedule in order to help your friend.

Georgia: wow you've been going to bed at 9AM and waking up at 6PM, whats going on?
Garrett: Yea I was sleepsitting my friend since she had an exam at 8AM yesterday.
