Question: what is strx on snapchat?
Answer: 'S' stands for streak. People usually send it to each other over the duration of a streak. I keep streaks in the same way, but I switch it up from time to time. I use either of the following: Streak, STRx, or S. Sometimes I draw an 'S' with my finger over top of whatever I took a picture of—and send that to someone.
