texting the water

Texting your friend a cautious 'Hey' when you haven't heard from them in an unusually long time, in order to check that they're not pissed off with you.

Often results in 1) a responding 'Hey' if clear of blame, or 2) pointed silence from the other party if you are guilty of an unknown offence.

Person A: Hey
Person B: YO WASSUP BRUH, AIN'T HEARD FROM YA IN DIZZAYS. HOW U BEEN MAN.
Person A: Soz man, was just texting the water to make sure you weren't mad at me for throwing up in your pool the other night. Glad we're cool

Person C: Hey
(No reply from Person D).

Additional information - Person C hooked up with Person D's sister and then never called her.
