phone check

Where one stabs another with a sharp object (shank). Attacks often centered around obliques (lower front and back sides). Called this because supposedly people watching out for this type of attack would duct tape phonebooks around their abdomen.

Person: "So it was a failed rape?"
Witness: "Hell yea, Mrs. Johnson's 9 year old son came outta nowhere and phone checked his ass with a pencil."

safety check

The act of going to the toilet because the impending fart is untrustworthy.

Good thing I did a safety check; there was some poop in that fart.

OR

I didn't need that safety check; that fart was all air.

Google check

Going to Google's site when you are unsure if your internet is working. If Google comes up, then you know you have a connection.

Lindsay: Its weird, I can't get to TMZ.com or Thesuperficial.com, but I have internet.

Paris: How do you know you have internet?

Lindsay: I did a Google check.
