Buttgating 

Walking so close behind someone that as soon as they stop you crash into them.

A guy was buttgating Selena. As soon as she stopped to check her phone he bumped into her so hard that she nearly fell over.

Buttfacing 

The act of providing oral gratification to your female partner from stem to stern while she lays spread eagle on her stomach and youre laying between her legs, also on your stomach. MUST be a female reciepent as preforming this act on a male may result in an unfortunate teabagging incident. This term is self explanatory and is ideal for any man with an oral fixation who likes the sensation of warm butt cheecks blocking his vision, or any woman who wants both ends of her taint thoroughly primed.

Hey Baby, roll over onto your belly so I can get to buttfacing you from your happytrail to the small of your back
