Someone who purposely attempts evoking "Darth Breather" in order to be recognized as one.

Breathing loudly hoping to get someone to call them "darth breather" (which means: someone who breathes deeply like darth vader) becuase they are completely obsessed with Star Wars, and absoloutly love it when someone makes a Star Wars reference especially when THEY are involved in the reference.

the LS refers to Luke Skywalker from Star Wars, also generally people named Luke love Starwars.
Luke: HUUUUUUUUHHHHHH HHHHHHHHHEWWWWWWW HUUHHHHHHH HEEEEEEEEWWWWWWWWWW

Lewis: Damn Luke you sound like darth breather.

Luke: YEEEEEEEEEEEEEEAAAAAAAAHHHHHH!

James(recognizing Luke's LOVE for SW): Nahh he's just an LS breather and get that tiolet-paper-roll-cardboard-lightsaber out of your mouth Luke.

Eric: sounded luke a vaccum to me anyway.
