Root Booty 

When a girl is standing up and her back is bent(ass out, head up) and someone opens a can/bottle of root beer, then pours it down her back starting from the bottom of her neck, as another person is at the bottom of her ass with his/her mouth open ready to sip down the root beer.

damn we should see how many girls would be down to let us root booty them.

Root n Boot 

Similar to the "One night stand" or "Booty Call"
Aussie slang for - To have sex with, and then kick out straight after
So, in essence - Hooking up with someone for one night of sex with no strings attached and hoping to never see them again.

Do not exchange personal info as this defeats the purpose of the good ol' root n boot

"Man, this girl is a hottie, but she has too many issues, definitely a root n boot"
