Lost in Translation

This is completely random, but funny. We're honeymooning in Montreal and awhile ago, I was online looking for good restaurants near our inn. I found a great looking one (can't remember the name now, of course). However, as I tried to translate the French on the menu, one particular item kept coming up and defying me. I still don't know what they were going for, but apparently this restaurant offers -

Caribou chili with beer gas explosions, served with sour cream and nachos

Whaaaa?
