A "Luban" is that complete lunatic that runs into a place, yells and demands
something without saying
anything relevant except for a massive
shockwave of made-up words in a high pitch - and everyone in that place knows exactly what this beautiful idiot wants - instantly.
"SQ@%×177HAVVA" - Look son, a wild Luban! He wants to buy a
pack of cigarettes.
"Allo blurrrghgg" - I'm
sorry sir, each household are only allowed to buy one pack of
toilet paper per visit.
