Almost agree with everything except with the jeje & the beki part, you don't need to jeje text or learn bekimon in order to "fit in".
I myself don't understand bekimon & don't use jejenese when I'm texting.
Siguro kulang diyan siguro is use the word "gago" whenever you're with your buddies.
"Gago pare ang init talaga!"
"Ui gago, chicks!"
"Gago ka talaga!" (laugh)
