This is a widely-used phrase in the gay clubbing community that refers to a brief (maybe 20-90 minute) nap, which someone takes in between two large events (e.g., dinner, raves, work shift, and circuit parties). Because both events will probably last for many hours, there is little time to sleep in-between them.
Yours truly took part in the act of this post last night. In preparation for a night out on the town, I took to the couch for a bit of respite, relaxation, rest. With the remote in my hand, and some cucumber facial creme over my lids, I was determined to catch some Z’s before heading out at midnight for some dancing. There are many ways to prepare for a night out-on-the-town, but the simplest and most effective will always and forever be, the “disco nap.”
1. noun: a short period of rest and/or rest, which is carried out in preparation for a night of clubbing, dancing, and perhaps, drinking.
Ex: “I had a really long day at work today, so I am going to have to take a disco nap tonight before we go out!” or “Gurl, I am fading from that last party, can we take a disco nap before we go back out?!”
