If a chick is on her period, and she just so happens to queef when you are eating her out, you have experienced a Ruby Shotgun.
Girl1: ZOMFG! I totally Ruby shotguned Brad last night. I so ruined his favorite shirt and Doctor said he'll have an eye infection for weeks.
Girl2: That's pretty knarl, I would tell people about this.
