Theme park bans thrillseekers from riding rollercoasters with arms in the air...

'Our rides are really scary and people tend to sweat more than normal due to the fear and anticipation they experience while queueing up so it can get really pongy.

Pongy?

I had to look it up:

pongy (comparative pongier, superlative pongiest)

(Australian, slang) Having a bad smell.
Eww, your shoes are pongy!

And do I smell a marketing plug "'Our rides are really scary and people tend to sweat more than normal"?
