WTF Is Portuguese Flannel?

Everybody needs a good flannel. How else are you be like all those rappers that brag about hooking up with hipster girls to, while wearing their flannels wrapped around their waists like they were Kurt Cobain doing an unplugged set? If you haven’t already, you need to get that one flannel that stands apart from all those simp plaids. Evidently this is a "Portuguese" flannel and, no, I don’t know what that means either. Whenever I hear Portuguese I just think about the age of exploration and like Henry the Explorer and shit. So I guess my 4th grade teacher did a pretty good fucking job, huh? Owen Elementary, where stars are born. Snatch this up with no regard like the Europeans did North American land.
