This band is insanely catchy. I pretty much associate them with riding in a car by yourself with blown out speakers dimed and screaming along with the lyrics, overwhelmed with internal energy and wanting to jump around and mosh while they play. They've been around awhile (10 years?!??!) and have some pretty cool stuff in their back catalog, all conveniently download-able from their Bandcamp/website for whatever you feel like paying. This album, specifically, collects some of their older songs rerecorded for the uninitiated and is a great starting point. Apparently their old incarnations included trumpets and stuff but AFAIK they're basically a three piece nowadays, which is my favorite amount of people for a punk band. No frills, nothing too complicated, just straight up pop-punk energy in packaged in accessible <3 minute songs. All their stuff is good, check out OK Smartypants which is another one of their completely solid albums.
