blue box

A tone generator built and used by phone phreaks during the 70s to illegally obtain free telephone service by synthesizing audio dial tones used for controlling switching stations.

The infamous hacker icon Captain Crunch helped to popularize usage of the blue box in the 70s, making AT&T's long distance phone service affordable for the masses.

Blue Waffle

Something that you should never look up on google images (seriously tho, this isn't a joke. Don't make the same mistake that I did)

Person 1: "I love blue food. I think I'm going to look up pictures of blue waffles right now to feel satisfied."
Person 2: "Geez! You're such a dumbass. Never look up blue waffles. I haven't been able to even use google since my incident."

Blue lock

Ohoho! Sounds like me! Radical individualism and ego! Hurray!

Hym “Yeah, no... Humility is for the NOT me’s. Blue lock sounds dope. I wonder how shit-brain Jerome is going to take it when he finds out there is a soccer anime about me and NOT HIM. That’ll be cool and will remind him that I’m better (which is what he needs to have happen) because nothing will ever be about him because he only regurgitates inane and trivial bullshit on a loop because his ideas are worthless. Like Dr. JeepJorp.”
