I see that to say GET OUT (or as you put it 'get the hell out'), you can say SOTI LA or RALE KO LA. I came across another creol word that meant GET OUT (jedpi or gepi?). Do you have other terms for the same expression? mesi.

Get out! (Scram!)
Bat zèl ou!
Disparèt devan m nan!
Pati!
Fè m pa wè w!
Kraze rak!
Degèpi!
Dekanpe la!
Bay teren an!
Bay tè a!
Rache manyòk ou!
Fann kò w non!
etc...
