|Ogres listen to Slayer. A lot.|
So I imagine: Ogres in a mosh pit, screaming at the top of their lungs like demons, ramming into each other, throwing each other around, a circling seething pit of ogrish sinew. The wandering adventurers come across them, assuming the worst, but the ogres, for their part, gladly invite the players in.
Of course, they might not "invite" them gently. A possible case of cultural misunderstanding? To a dude eight feet tall and built like a brick shit-house, gently could involve all the grace and care of flinging the worried onlookers right into the midst of the circle pit. Or it could involve the headbutt, a common Ogrish greeting amongst equals. It could involve a chorus of bestial, gleeful screams, delight at new participants into what was already a rip-snorting party.
Ogres live a harsh life, but adventurers who don't speak Ogrish lead harsher ones sometimes.
