MT can be short or microtransactions and is sometimes used to refer to the sale of virtual goods in online games, like World of Warcraft.

Money to spend. Significantly characterized by a person or persons who has nothing to do but spend ridiculous amounts of money. Not necessarily in the ultra-rich Paris Hilton super star manner.

Must be nice!!
Normal person: Hi MTS friend, I just got home from work. What did you do all day?
MTS person: Work? what's that? Well, today I went to the gym for pilates, went to the spa for my nail and facial treatment, stopped at home to make sure the nanny wasn't letting the kids watch tv all day, met (name random mts friend here) for lunch at Cheesecake factory, and then went to Nordstroms to pick up a tie and some new socks for my husband!"

Message Too Short

Usually, this term is made for posting in the forum, and it has character limits, from 10 letters to 2000 or so; if you write 4 characters to reply, it will disallow you to post because message is too short. So you just add "mts" after your message.
