I finally thought of a usable nickname for my older brother - Flanders!
Ramone has always loved the Simpsons, even though we weren't supposed to watch it. (Dad would tell us to turn it off, but we didn't pay much attention to him as he was usually laughing.) He (Ramone, not Dad) gave us all Simpsons names. Dad = Homer, Mom = Marge, Ramone = Bart (that one was pretty close), Me = Lisa, & Peanut = Maggie. We ran out of family members so the eldest was given the name of Flanders.
So, there you go, older brother - you are now Flanders.
