Sure, no worries! I haven't been disappointed yet by responding to downvoted comments so I will keep doing it :)
Just another similar metaphor: Power hungry. Not the stove kind but the dictator kind. To be honest, there are quite a lot of body related metaphors, e.g. drowning in trouble, blinded by ambition. I guess it comes down to evoking some strong emotion.
Totally agree, though I haven't really participated that much on Reddit. Seems like any disagreement is quickly framed as trolling over there.
