When one person takes a shot through a straw and spits it into another persons mouth. Just like a mommy bird does to their baby.
Ben: the fuck are Jamie and nick doing with the tequila
Kriiiiten: that might be what the kids call “baby-Birding”
A vomit burp. Or basically like mother birds that regurgitate food for their young...
"you look sick, are you going to feed the baby birds?"
*burp
"ew I just fed the baby birds, tasted like Wendy's"
"did you smell that?!?! I think Ryan is feeding the baby birds"
When two guys receive a blowjob from the same girl. Similar to Eskimo Brothers, but called Baby-Bird Brothers due to the similar action a mother bird uses to feed her young.
Guy 1: "Hey I got a blowjob from Shaylyn."
Guy 2: "No fucking way, me too!"
Random bystander: "Dude, you guys are Baby-Bird Brothers!""
When someone drinks a beer and spits it into your anus
I would really appreciate it if you could get me intoxicated by performing a baby bird butt chug.
When you are hitting it from behind and cum, then the ole lady coughs and you catch it in your mouth.
Last night I had the ole lady bent over the trailer hitch and I came in her, then bent over to smell her ass and she reverse baby birded me.
When someone spits in your mouth having just recently eaten
"He was eating something gross and then just straight up baby birded me"
When you accidentally vomit in someone’s mouth during a drunken makeout.
Dude, I was so drunk last night I thought I regurgiburped but actually I was baby birded by a ladyboy on Silom Soi 4.
