A phrase derived by those who have experienced the intensesexual frustration of waiting for a girl to be ready to have sex again, only to find out she's on the rag.
Girl: "Shelly, did you have sex will Bill last night? I heard he's been waiting for like a month for you to get back in town."
Shelly: "Girl, he can wait. I wasn't in the mood anyway- its that time of the month.."
Girls' Simultaneous laughter: "Saved by the Red!!!" (high-five)
(Bill wimpers softly in the corner...clutching his blue balls.)
Girl in Red is a singer who is a member of the LGBTQ+, so if a girl asks another "girl in red?" she's basically asking her if she's into dating/likes girls.
girl one: "girl in red? 👉👈"
girl two: "hell yeah!"
When you get drunk (or just ED) and your penis stops working just before you're about to have sex with a chick. This causes great embarrassment and you will forever be known as the guy who can't get it up.
Evan: Freshman Red exists--it's a real thing.
Drew: Freshman Red does not exist, you just have ED.
Evan: Sad face.
