(Simple):

A Torrent Whore is a BitTorrent user , who is too lazy to upload his own content, so they opt to download a torrent from another user, and use those contents to create another torrent upload in their user name.

Definition (Extended):

Instead of creating their own rips, Torrent Whores merely download other people stuff, rename it and post it again as their own. It is sad, since it generates a lot of unneeded duplicates, instead of allowing larger swarms to develop around a single posting.

They are never going to give credit where it is due, since the folks who do this are trying to make themselves into bigshot uploaders without bothering to put in any real effort.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
