It's when someone is so into sex they text, call, and DM like they're the only person on the planet
'I'm texting you because I can't stop thinking about sex.', said while eating cereal
'You didn't answer my call? I'm texting you again.', sent 10 minutes later
'If you don't call me, I'll scream your name in the shower.', said with a straight face
