The art of avoiding eye contact or using something to block your vision to prevent seeing someone or something that will cause you to become trapped for a long time preventing you from continuing with your task or limitations.
I saw an old high school classmate and I had to bird box them so I wasn't trapped into a "How have you been?" convo.
I saw a sale at the store, but I only have enough to pay my bills this check. So I totally bird boxed past it or I'd be broke.
The act of imitating the movie Bird Box, and challenging yourself to complete an otherwise innocuous or petty task while blindfolded.
Guy 1: you wanna try the Bird Box Challenge?
Guy 2: Sure, what do I have to do?
Guy 1: Put on this blindfold and try to cross the street without looking.
Guy 2: Sounds kinda dangerous.
Guy 1: You never know when you'll need this skill man. Everyone's doing it!
Guy 2: Ok... **(puts on blindfold and starts walking across the street, then gets hit by a bus)**
Guy 1: Beautiful.
