As Bros before Hoes states; "your bros (male friends) should always become before hoes (female with whom you are/hoping to have a relationship with)." While Bros before Hoes is indeed the most hallowed of traits amongst Bros, what must also be taken into consideration is the bro-ness level of the invoker of Bros before Hoes. That is, if a male cohort of yours wishes you to disengage from a female you are courting by claiming "Bros before Hoes," yet cannot be considered a "Bro" himself (e.g. He wouldn't do the same for you, you don't know the guy too well, he's cockblocked you on more than one occasion, etc), then you have the right to proclaim "Pussy before Wussy" and continue your pursuits.
Man: "Nah, I'm goin' out with Jen tonight. Gonna finally pop the question."
Douche: "That skank?" Come on, man, Bros before Hoes."
Man: "You smoked all my weed yesterday, hit on my sister last week, and I've only known you for a month. Pussy before Wussy, bitch."
