I just read a 2 x reader fanfic and it was so good I was giggling and kicking my feet the entire time (the writer said that English isn't their first language)
drew the most horrifying thing in gartic phone bc i was forced to. they kept begging me and annoying me in vc i had no choice. i regret drawing it so much dude why..
To answer your question; pg'ing is the a thing where you guess someones password. most usual pg'ed accounts are from old ROBLOX accounts. Yes, pg'ing does mean "password guessing/guess"
