These are any pair of pants that will cause potential mates to not want to have sex with the wearer. A typical example would be a tight pair of jeans that have some sort of weird design on them and are worn by a straight male. However, there is not just one style or brand of pants that are birth control pants, and the exact definition can vary across cultures and time periods.
Katie: “I was attracted to Johnny until I saw him wearing those weird skinny jeans.”
Jenny: “You mean his birth control pants?”
Mark: “I wear my birth control pants out to the bars just to be safe.”
When a girl only dates guys beneath her because the birth control she's on has her hormones so fucked up that she's attracted to the pheromones of weak, feminine men. These relationships typically end after the girl stops taking birth control as she discovers how naturally repulsed she is of her sissy bf after the fact.
Similar to "chocolate-covered raisin" relationships. You could put chocolate on anything — caramel, marshmallows, peanut butter, etc — putting it on a raisin is just insulting.
"Why is she dating that guy? He must be really funny, have a lot of money or a big donkey dick."
"No he's a loser, it's a birth control relationship."
Times in your life where you observe someones child out of control, acting out irrationally, throwing a fit or otherwise making you wish you didn't have kids (or glad you don't have them)
Wow, sitting on that 12 hour flight with that baby crying nonstop was a birth control moment for me!
The act of ejaculating so many times after your baby is born that your sperm turns red and your baby is now the spawn of Satan
"Hey Johnny bear how was your sleep"
"I had no sleep I was in Post-Birth hemorrhoids"
"Lmao ratio+L"
Poetic way of referring to the beginning of a physical existence or a new phase of life.
Free from this suffering only when death rips my soul out, body birth!
The act of defecating on people whilst crowd surfing
"Did you see that guy at the music festival last night? he was crowd birthing, the dirty bastard."
