An awkward boner occurring when in a close situation with a close friend, such as a hug or spooning. It is not caused by intimacy and can also coincide with the random boner which has happened at an awkward time.
It is polite to inform the friend that this situation is boner weird, so he/she is not disgusted with your random erection.
guy one: I have to warn you, this hug is boner weird.
guy two: It's ok, we all get boner weird every once in a while.
Guy one: See that guy over there, why has he got an erection in the swimming pool?
Guy two: Oh that's just Harry, he's always getting boner weird.
Boner brew is your finished product after your brew (masturbating). Think of when you brew beer or tea to get your finished product. Same if you're making your boner brew, you get cum! Hooray!
I was in my room making some boner brew to Brazzers when all of a sudden Godzilla rips the roof off of my room and snatches my phone away and tells me to settle down, I've made like 5 brews today.
