Text Silence 

A prolonged period of time in which the person you are texting does not respond without giving a reason for doing so. This can occur in any type of messaging.

"So I was texting this girl last night and after i texted her asking to hang out there was like 10 minutes of text silence"

When Darlene starts texting in a group text and everyone stops because she is an idiot and no one likes her

We were all laughing our asses off in a group text until Darlene said something totally stupid and there was an immediate text silence...
