the underage riff-raff that hang out at 24 hour Tim Horton`s locations during the late night/early morning hours of the weekend. They are usually drunk, stoned, high, or a combination of any of the above, high-school aged kids who dress like whores, hence, "Timmy Hoes". Usually order mass amounts of baked goods to suffice their munchies.
Friend 1: I saw Shanna Friday night at Timmy Hoes
Friend 2: Yeah, she`s such a Timmy Hoe!
