...I gave the meme a check because of how silly it looks like. Apparently it's a visual pun, the text can be read like "be a man" (i.e. man up) or "be a leg".
The modlogs of the other comms are equally crazy! I'm genuinely laughing - the guy is clearly trolling. Kind of expected, he has a comm for conservatives. O.o
I also like this sort of pun - for Portuguese there's a whole comm of those in Lemmy, !tiodopave@lemmy.eco.br. Some in the same style as the meme, here's an example:
Rough translation: "The Christmas cement mixer is now on your screen! May all your dreams become concrete" (with "concrete" as both "real, palpable" and that cement mix)
