Well, here are products with Japanese writing on them. But these do make sense in Japanese. These say "Sukebe". There is no single English word that this translates into. It roughly means "pervert", or "lecher", or maybe "horny person".
If somebody calls you a sukebe and they are smiling, then it is in fun and probably a light hearted compliment. It is not gender specific, so could mean a horny girl or horny boy, or maybe something like "sex fiend".
