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.

blood check

The act of checking your face to see if you're bloodied. Whether it's rooting around in your mouth to see if you've loosened a tooth or checking your fingertips for blood after taking a hit to the face. Commonly used among hockey players.

"Damn, Probert really had a go at him. Look, he's pulling a blood check. Why even bother?"
