A cheerleader is supposed to be peppy and enthusiastic, whereas someone on crack would be high and have erratic behavior, so a cheerleader on crack would be even more enthusiastic  and upbeat
Context: "I try to sound downbeat even though I'm angry."
Hypothesis: I swallow the anger down and force my voice to come out like a cheerleader on crack.
Based on the context, is the hypothesis true, false, or unknown?
