For a Russian Huel is even more off-putting, "ohuel" (охуел) is a swear word which roughly means "out of his mind", derived from "huy" (хуй), which means "dick".
I don't want no dick in my food, thank you very much.
Does the word mean something different in England?
I think they may be correlating it with the similar sounding word “hurl”. Huel on the other hand is readily available in shops in pre-made form, and I’ve seen it in vending machines in Heathrow.
Maybe it's because it sounds like 'gruel', or the sound of vomiting.
