Yes, you did read that correctly.

Men are raising awareness about cancer.

Maybe raising isn't quite the word I'm looking for, but then again, maybe it is. :-D

Yes, men are just doing their part in calling attention...ahem...to testicular cancer by posting photos of their penises in socks at #cockinasock.

The idea is to bring people to justgiving.com:

Hello and welcome to the 'Cock in a Sock' JustGiving Page!

This campaign has gone viral on Facebook and is growing across the social network community. Our supporters are amazing, donating and sending in their 'Cock in a Sock' pictures to raise awareness for male cancers.

Please donate anything you can, and help us raise the 5k we need to become a registered charity!!

All donations made go directly to Cancer Research UK

P.S. According to buzzfeed.com, Instagram has blocked the tag and apparently deleted all the photos that were tagged #cockinasock. but find them on their Twitter.

Also, find the photos on buzzfeed.com.
