No meaning mawsrat??? Give me a break, even if you had no meaning originally, It has one now. With tongue planted firmly in cheek, let me put on my psychic hat on and give a reading on your name:

maw Pronunciation (mô)
noun
1. The mouth, stomach, jaws, or gullet of a voracious animal, especially a carnivore.

Conclusion:

At the poker tables you are a carnivore. and the last part of your name is "rat", which implies that the carnivore you are, really likes the turn card, and really really loves the river (hehe, river-rat).

You're a presence on any poker table. That's for sure!
