Crush Code Names???

Okay, so rn I have a wee little crush. Nothing serious i don't think but who knows where that will go. Anyways, I need a code name. Right now i'm just using the name "Rainbow Dash". It's because he kinda reminded me of Rainbow Dash (from MLP) but now I'm second guessing it. When I really think about it he doesn't remind me of Rainbow Dash like at all. if anything he reminds me of Apple Jack. I do have an idea though. I know I wanna keep it My little pony related. Cuz I think that's cool and it fits. Other than that I'm open to anything. I feel like it should at least be the name of a character that shares some qualities and/or traits as him. I would give details on personality, but I I don't know a while lot about it. Either way I need a code name, so any suggestions?
