A generalized genre of music referring to "newer" mainstream punk. From the tendancy of breakout punk bands in the last several years to include numbers in their name (i.e. Blink-182, Sum 41, etc). However, a band does not have to include a number in it's name to be considered "number punk"; the genre in general references popular punk, in most cases signed to a major record label. Read: good music.
