Vagel train

The vape bagel train. A group of bros go to a bagel place and line their bagels to mouth height. A person hits the vape into the bagel holes and it passes through the holes into the other bro’s mouth. He hits his bro’s hit and blows it back, forming the ultimate bond of manhood. Immediately after the act, both bros and all witnessing bros must say “no homo” then eat the bagels.

Let’s go to the Bagelry and hit a vagel train!

Bro! That was a sick vagel train, no homo though.
