Jewtentacles, or 'jewtents' as it is known by some of its members, is a community on the popular blogging site livejournal which is both a rating community and a place for talking shit about other livejournal and myspace users. There are disucussions about SIFs, uglies, fatties, fupas and other generally unattractive characteristics of livejournal users.

This elitest community allows a very select few to even apply, and an even smaller amount are accepted. All things within the community are very confidential, and most of the members are friends.

The members of Jewtentalces are also known for 'invading' other, less-selective rating communities, with a high percentage of people they deem 'ugly.' These 'invasions' take place over a week or so, in which all members will apply, and due to their attractive nature, will all be accepted. Then, the ugly members are challenged out and plenty of 'LJ drama' is started. The result of these invasions is oftentimes the closing of the community.
