I call them “scooter people,” as in “I see scooter people.”
Been on a cruise recently? My God! The disgusting fat hogs lined up at the buffet is a sight to see.
You just reduced my desire to take a cruise. I took one last year on a Spanish cruise boat. There were a few plump ones, but not all that many. A worse esthetic problem was that women in their 60s and 70s felt obliged to wear skimpy bikinis at the pool - best passed quickly with eyes averted. The biggest problem was that stand up comedy in spanish isn't all that funny when you don't speak it.
