"Tuff Tumas" is also the name blong wan DJ.
Bislama is so neat because although it has a HUGE amount of vocabulary in common with English, the underlying grammar is Melanesian. Plus it's evolved from a pidgin, through a creole and into a full blown language.
Sometimes people hype up the "funny" phrases to entertain tourists, though I find it kind of cringy. Nobody says mixmasta blong Jisas outside of corny tourist brochures. Helikopta is a perfectly cromulent Bislama word.
As English speakers learning Bislama (as well as Tok Pisin and Solomon Pijin) just remember that false cognates are everywhere.
stap kwaet nomo means "just be quiet."
In PNG Tok Pisin, there's an interesting contrast between lukim and painim. Lukim means see/watch/look, and painim means to search. So mebi yu save stap painim painim i go tasol... lukim... nogat!
And although PNG, Solomon Islands and Vanuatu have (mostly) mutually intelligible versions of this pidgin, they're not at all the same thing. If you have a whole lot of something in PNG, you have plante. In Solo, you have staka and in Vanuatu you have fulap.
And in da ʻaina, you get choke. Bula fo bumbye we get choke melomelo.
