Honestly you're just all the more unique if you don't have one, but perhaps 'Skinner' would be a fitting nickname.

"Chipmunk" is Lauren's scout name. Her dad is "(Big) Lizard" and there's a handful of npc scouts working in Scouts Inc. with the names like "Mink," "Ferret," and "Cat." Adorable climbing code names for their customers. You know, its kinda like going to the strip club and asking for 'Taffy' or something lol
