Get the yoedmug. The uncommon abbreviation for someone who's first initial is A. and who's last name begins with the letters 'y' & 'o'.
Goofus: Man, I wish there was a way to quickly address all my friends who's first initial is 'a' and who's last name begins with 'y' & 'o'.
Gallant: Listen Foolio, that's totally possible; don't you know about the uncommon abbreviation for names that have a first initial 'a' and a last name that begins with the letters 'y' & 'o'?
Goofus: Playa, It seems like it's uncommon because that is not a common combination of letters for someone's name.
Gallant: Slow your roll, Hustla. You're the one who felt like you needed a word to address ALL your friends with names with that letter combination.
Goofus: I'm tired of this, just tell me what it is.
Gallant: It's 'A Yo', alright? Thanks for sucking the fun out of this, fun ruiner.
