Kids,

I'm going to say this once, and hopefully it'll correct a lot of ills out there.

And, this sign:
Are not the same thing.
The above is the American Sign Language for "I Love You". Yes, it's both touching, and beautiful.
The lower image is of "La Corna" a derogatory hand gesture to symbolize horns, also used as the sign of the devil at rock concerts such as Slayer.

If you want to tell your deaf girlfriend something touching, you use the "I Love You" one. If you want to stick your tongue out and look hardcore in a photo with your friends eating MacDonald's on a streetcorner, you use the "La Corna" one.

Hopefully this tutorial has saved a few more geeky white guys the pain of saying I love you to the lead guitar player in their favorite thrash metal group.
