at one moment I was playing toribash (for the first time) and there were a bunch of random "lines" coming out of the little player, is it supposed to be that way?

Hmmh, I don't really get it...
Could you take a picture of it?
Also, do you have the newest drivers for your graphics card?

These are most likely artifacts.

JPEG artifacts are areas in an image with a blocky or blotchy appearance such as what you can see in the extreme example on this page. JPEG artifacts are the result of an agressive data compression scheme that discards some image data. This is known as "lossy" data compression. Several types of artifacts can appear which are noise around edges, blurring, a smeared appearance, color distortion, and/or checkerboard-like blocking in busy regions.

Compression artifacts occur in many common media formats, including JPEG images. When artifacts are present in other still image formats it is most likely because they have been converted from a JPEG file at some point in the image history.

I figured out the problem, just needed a simple restart, the joints were screwy
