When you and your boys get together to chill, but y'all's love language is physical touch but not in a gay way.
Dude A, Dude B, and Dude C brolone yesterday and dude A tickled dude C while watching UFC 290 dude B laughed and said "gayyy" the. Dude A & C ganged up on Dude B and tickled him and they all laughed. After brolone time they shotgun bud light and regretted it... The beer the not the brolone time.
A weirdway of saying, "brother from another mother".
Only people who are not actually related to you are referred to this way.
It can also only be used as a direct statement to someone, you can't refer to people like "he's my brolander" or anything like that, and if you do, you're a savage.
