Snooki to Jeans Co. -- Stop Trying to Get Me Into Your Pants!!

Snooki swears she's NOT an Obscene person ... but she claims the Obscene Jeans company used her name to promote the brand anyway ... and now the MTV star is calling them out.

It's all over a press release Obscene sent out Monday -- announcing a new product placement deal with Celeb Branding, LLC to "outfit the female cast members of 'Jersey Shore' in its hottest new fashions." The statement mentions Snooki, Jwoww, Deena and Sammi by name.

But Snooki's rep claims Snooki has NOTHING to do with the company and it had no right to use her name.

The rep tells us, "The inclusion of Ms. Polizzi's name in the announcement was unauthorized. Ms. Polizzi has never been approached by the company."
