(And, no. It's not the same thing as a rainbow party, pervs.)
According to Urban Dictionary, a stoplight party is defined as follows:
A party where guests wear the the colors of the traffic signal to denote their relationship status: green means they're single, red means they're taken, and yellow means their relationship status is "complicated."
OMG, that's genius! Much better than my MENttens idea.
The only problem is that I look terrible in red. Good thing I wouldn't have to worry about that right now anyhow. ;)
Had you ever heard of this whole stoplight party thing before?
(And wouldn't it be a bitch if you went with someone you were dating, but they showed up wearing yellow?!?)
