Howdy folks.
I'm translating a show from Japanese to English, and there is one banner sign I am kinda stuck on. I will reference the situation in case that will help the context of the sign. Members of the students association are searching for somebody that has been breaking campus regulations. The banner reads:
耳スリ締り強化
耳 on it's own mean's ear. スリ is confusing me here, because it's in Katakana. I am not sure if it's together with the previous kanji or if it's a separate word. Neither of which I can find reference to in my dictionaries, WWWJDIC, or my JquickTrans program. I know Katakana is mostly used for foreign words now, could this perhaps be the Katakana writing for the english word 'three' ?
締り I don't know if it's irregular kana use, or if this means something specific that is not in my dictionaries. The kanji alone means tighten/lock/tie etc. It's used in a bunch of words, and was used on a previous sign 取締り meaning management in the previous context.
強化 means to strengthen or reinforce.
As a last ditch I tossed it into babelfish, which seems to sometimes help me with odd words I am not familiar with, what came out was no help: Ear スリ tighten strengthen.
Could somebody please help me to piece together what exactly this banner is saying? It's the only one in this show that is confusing me.
Thanks
