text pressure is when you are with a group of people that are texting, and you feel obligated to take out your phone in order to be equally cool and not stand out from the rest.
dude1: who are you texting?
dude2: my friends kristina, kate, matt, and jen.
dude1: oh thats cool... *takes out phone and scrolls thru contacts*
dude2: no text pressure, bro!
