A phrase used whenever someone coughs or exhales onto the bowl, blowing it everywhere. This is an extremely noobish thing to do. If you blow a bowl after your third time of smoking, then you should probably quit/run away.
Person 1: aight dude your new piece you can have greens
Person 2: thanks man
(Person 2 hits it and coughs, blowing the bowl)
Person 1: wow dude you just blew the bowl
Person 1: and i gave you greens
Person 2: uhhh whats happening?
Person 1: youre done, ya, youre done
