Help me understand acronyms and their meanings...

[SeaYouSalty]

If someone would be kind enough to tell me the slangs and descriptions of these acronyms would be much appreciated.

OGE - ?
TID - Transaction ID
Changeable email - I thought FA accounts couldn't have a changeable email?

And any other slangs or important terms to note

OGE - Original Email
FA is full access, make sure you get OGE tho
You should know BIN and stuff like that.

Kavish Thx, I know BIN and all that but if I have an og email what does it mean exactly, like do I get access to an email or something, I'm still confused . Sorry for wasting your time.
