sock filler

A (generally) teen-age boy who spends the majority of his time masturbating into a tube sock. Sock fillers tend to be socially awkward, often standing slack-jawed while in the presence of their female classmates.

"As the girls' P.E. class ran past, a large number of sock fillers began to shift uncomfortably and mumble to each other."

album filler 

When a band releases an album where there's only a couple good songs, and they need more to make a whole album, so they make crappy songs knowing they aren't that great just to complete the CD since you need at least around 8 songs for a good CD.

The Shins' new album "Wincing the Night Away" has only a few great songs on it, and around 15 tunes in total, so they make a bunch of album fillers in order to make it a full-length album
