One who is undefeated, virtually "beat free", and/or will never be beaten.

Originally came from a mispronunciation of "The Beatles".

If you use this word without knowing it's definition, consider yourself to have had a blond moment.
S/he is our secret weapon, s/he is Beatless.

Get the Beatless mug.
John, Paul, Ringo and George
Listening to The Beatless again now with my daughter, I am amazed by their perfect simplicity. Heart-warming, hopeful, conscious, comforting.
You should hear her trying Yello Supp Marie or Oyo needles Luvv. ♡
