The unwritten law that your fries (female friends) should always become before guys (male with whom you are/hoping to have a relationship with). Most used as a trump card by your fries when they feel you are becoming whipped.
Origin: "Bros before hoes" for female.
Erica: Jane, it's ladies night, remember to bring the wine.
Jane: Sorry I can't, Jack wants me to go to his place.
Erica: WTF, fries before guys, I will see you at 8.
Jane: Good call, see you at 8.
