What is Express Crush?
1.
A feeling of attraction towards an individual after meeting them once or twice that usually lasts for approximately 24 - 48 hours and then fades when a new individual enters the picture or the weekend is over. This feeling of attraction is usually sexual in nature and might lead to a make out session or a one night stand. Typically, an express crush is one of convenience hence the name "express crush".
Man, their friend Johnny was so cool last night. He brought everyone a round of drinks and stopped that nasty guy from hitting on me. I can't believe that he is leaving in 2 days to go back home. I sort of want to make out with him before he leaves. I totally have an express crush.
