I don't have class on 3rzda, so maybe we can hang out then.
|HAGW||Have a good week|
|24/7||Twenty-four hours a day, seven days a week|
|SMTW||Sunday, Monday, Tuesday, Wednesday|
|TGIF||Thank goodness it's Friday|
3rzda is a phonetic way of abbreviating "Thursday." Like 2zda, this term does not have a "y" at the end of it, perhaps to make the person using it seem "hip" or "cool."
If it's 3rzda, that means it's almost the wknd. Tomorrow, you and the person you're chatting with can TGIF.
