They're ♥♥♥♥♥♥♥ ugly

You know those grenades, that serve mere cosmetic purposes on soldier, pyro and demoman? Even though there are no grenades in the game - none that you can actually use - the ones pinned onto the clothes of soldier and pyro are a nice addition, they provide some extra detail to the characters. But let's be honest, the ones on demoman are obnoxious. They are big and round, like some kind of stupid toy, and there's way too many of them. Hence, this community of fashion-aware players is here to publicly criticise their existence.

Luckily, there are a number of cosmetic items that change, or even better, completely remove the ugly-ass pipes from your demoman, so go put on the juggernaut jacket and remember: ♥♥♥♥ the demoman's grenades
