Mario and Luigi will ever get married?

I don't think so.
If they get married, probably they would stop going to adventures.

Luigi sure Mario nahh cause when peach, pichi is walkin down the isle Mario will blink open his eye and see hujambo punda (Sorry for lango) get kidnapped AGAIN
so if wewe ask me peach, pichi with Marios ring on her finger impossible until
A.Mario Kills Bowser
au
B.Nintendo stops Mario games (NEEEVVVER)

Okay if wewe mean to each other, all I have to say to that is ew, they're brothers.

If wewe mean separately to other girls then why not. It would be cute.

Want people to call Mario "Pedo-Mario" and Luigi "Gay-Luigi"?

Not to each other, but maybe to peach, pichi and Daisy

Never. The Super Mario Brothers are staying cool and single forever! Like Me! :-)! Taking care of business, helping doing away with evil. - Making the world a better, zaidi beautiful place. <3. XOXO. :).
