Essentially, a tard bait is someone who would attract, or "bait" someone who is mentally retarded. This can be done so by acting like a retard, physically, or mentally, by acting like an unstable mentally ill person.
Trina rocked back and forth while yelling "Gail Swallows!". This would turn a retard's crank, therefore Trina is Tard Bait.
