Whenever I get bored of reading jargon-filled emails at work, I imagine those acronyms mean something else — or, are euphemisms for underlying annoyances.
TTYL (Talk To You Later) - Ta ta, you losers.
ASAP (As Soon As Possible) - As Slow As Possible (often turns out to be true)
IMHO (In My Humble Opinion) - I'm Humble. Occasionally.
FYI (For Your Information) - F*** Yourself, Idiot.
WRT (With Respect To) - Wearing Red Thong (this works beautifully at times)
It's fun re-reading those mails with these acronyms.
