Celebrated in song—the rock 'n' roll classic "Louie, Louie"—this is a gregarious, friendly spelling of Louis not often used as a full first name. It reentered the US Top 1000 in 2015. It's a highly popular choice in England and Wales.

This name, more recognized as a short form of Sebastian, is perfectly usable a cool full name, and, in fact, ranks on the UK popularity list. Seb is getting lot of attention as the nickname name of the Ryan Gosling character in the hit film La La Land.

Fleet is one of the uncountable number of new word name possibilities, and a particularly cool choice at that. Connoting speed, Fleet beats Rush any day. Might be short for Fleetwood, but we prefer it on its own.
