When your bros jizz in your protein shake for extra protein.
"Bro do you think I can get some jizz for my Brotien Shake?"
"Of course dude."

Get the Brotien Shake mug.
When working out with a group of friends and one makes your post-workout shake for you just to be nice

Also applies to a Brotien Bar when one of your boyz unwraps a protien bar and hands it to you.
Skyler puts hella berries in the brotien shakes he makes me after we hit the gym. thats why brotien shakes taste so much better than protien shakes.
