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.
