A term used in a Surreal Comedy video by Timotainment directed toward the "Meme Man". It is likely an insult used toward those who violate simple instructions. It also has a sister insult, Clampongus, which is used in similar context.
"Dave is such a blongus, he keeps absorbing all of my geometric shapes even after I tell him not to."
"Stop ascending into the (8^6)th Dimension, you blongus! Any higher and you might even be a clampongus! damn you!"
Ben: i touched the orb after being told not to, now I'm in jail.
Jeff: why did you do that?
Ben: idk
Jeff: you fool, you blongus, you absolute utter clampongus.
Basically used when an authority that doesn’t like swearing is around but you really want to call someone a prick. Can also be used just to spice up your vocabulary. Each word can be used individually
