The biggest cock block of ALL TIME.

They make you unable to kiss anyone for what can be weeks.

They also somehow know the exact moment that will cause the most detriment, and will crash your face like it's nobody's business.
As I write this I am being cock blocked by my cold sore because there is a very fit girl in the next room but I can't get busy with her. FMLip.
