Bash

Self-assured and playful, Bash is a short form of the popular Sebastian, sharing the same energy as Dash, Colt, and Nash. It could work as a quirky, rough-and-tumble alternative to the more familiar nicknames Seb or Baz, or, for those looking for something unexpected and adventurous, it could be a stand alone choice.

Beyond its ties to Sebastian, Bash could also be considered a word name. This gives it a number of meanings, including: to strike or thump someone; a party or gathering; an endeavor, or to have a go. These meanings might put some off using Bash on the birth certificate, though for others, it could give it an energetic and confident vibe.

Associated for some with the long-running comic strip The Bash Street Kids from the British comic, The Beano, Bash has also featured in the Thomas the Tank Engine Franchise and in the American comedy Franklin and Bash.

Quietly used since 2014, Bash was given to 21 babies in 2022, though more recently, it has been declining in the US, given to just 10 boys in a recent count.

Pronounced BASH.

As of October 2026, Bash ranked #6494 in US births in 2025 SSA, peaked at #4651 in 2021.
