Acronym: pretending to be asleep
If you’re supposed to be asleep but are instead on your phone, trying not to attract any attention to yourself, and your friend is calling you or sending you attachments with loud audio, just hit them with ‘ptba’!
Stella, texting her friend: Listen to this new song I found! I really think you’d like it.
Jessi: Sorry, can’t now, I’m ptba.
