Some people know their weaknesses and are not afraid to show them. Or, you know, tattoo them in a big bold Hebrew font on their arm...
Don't know what other weaknesses this victim has, but bad knowledge of the Hebrew language is certainly one of them.
His tattoo has three totally random words in Hebrew. The first word, "Hulsha", means weakness. The second word, "Mkubal", means accepted or popular. The third word - that one is just an incorrectly formed nonsense word that has no meaning.
How can this even happen? I would have blamed some automatic translation service, except I don't know how to explain that last gibberish word. Very strange indeed.
