I guess she means tomorrow,.

FWD: Hey hun. What r u doing? I'm in a big jam and don't know what to do. I'm down a sitter 2moro.
7:30-12:00(around).
from an 860 phone number, Thursday, July 22, 8:05 PM EST

I like how 860 has to clarify that, when whoever sent her this text wrote "2moro," she might have meant "tomorrow." It was so unclear.
