Then I came up with "Va-Guy-na". It's basically a MAN-gina, but I changed it so it's totally my own. "I pleasure the ladies with my large va-guy-na". No? Fair enough.
How about "Man-iscule"? It could mean something like a short dude or something.
Maybe "Oni-MAN-opia", a dude that looks the same forwards and backwards. Or maybe wears all of his close backwards?
Anyway, I can't sleep. Inso-MAN-ia.
