sonic rainboom 

When your banging your partner and then soon you start shoving your penis into her anus, and you try to shove it until it touches her sphincter, and then after minutes of shoving, you cum a painful stream into her anus. Named after the aerial stunt from MLP: FiM.

Last night, dude, I started giving your mother the sonic rainboom and she was like, "OWWW!!! STOP IT!!!!".

Sonic'd 

1. The act of purposefully avoiding asking someone on a date that is mildly interested in order to build intrigue for the eventual asking. Usually waiting past the point of disinterest, annoyance, impatience and insignificance because you're not being asked until there is a want to be asked out.

2. When someone doesn't ask you out long enough that you are almost busting at the seams for them to ask you out

Root being the Sonic introducing its commercials in the NY Metro area years before a Sonic was built in the NY Metro area. That by time a Sonic was built, everyone felt a need to be at one

"Wow, Tony finally asked me out on a date. I've been waiting so long for this I'm excited"
"You totally got Sonic'd"

Sonic braking 

The act of honking your horn rather than hitting your brakes when approaching an obstacle on the road.

*Long honk followed by a car crash* Looks like that guy tried sonic braking. He didn't even slow down before hitting that truck.
