Those little annoying pieces of fucking shit that come live on you're lip (uninvited) for 2 weeks.
They fucking suck
They come at the worst fucking time possible.
Like when you get a new girlfriend.

And you don't want to give her a cold sore.
So no kissing.
And when you go to a new school.
You have a huge fucking nasty lump on you're lip.
They suck ass.

Cold sores suck fucking ass they are bull shit......Non of the medicines work.

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.

Common version of Herpes Simplex Complex 1 (HVC1). A highly virulent virus.

Most common form is a red blister-like sore on or around the mouth, but it can show up within the mouth and on other areas of the face as well. Typical symptoms last 8 to 12 weeks, in which the virus swells, breaks, blisters over, then disappears. Before showing up, the virus makes the skin tingle or itch.

Extremely transmittable. Typical infection occurs with skin-to-skin contact with someone who already has the virus, but can also be spread using utensils, bottles, lip stick, lip balm, pipes, ETC(...) that an infected individual has used.

Transmission can be prevented not engaging in kissing or oral sex with a person experiencing an outbreakl, not sharing drinks or other objects that could be in the mouth, and washing hands often.

HPC1 is estimated to have infected 80% of people living in the U.S. Personal opinion: they're not a huge deal.
I would love to kiss you, it's just that... I have a cold sore.

Oh, that's alright. We can just cuddle for now.

The most annoying motherfuckers you'll have on your lip.
People who've never had them in their life should consider themselves lucky. You'll think you're good because you haven't had one in a long time but as soon as you think that, one of these fuckers will unexpectedly grow on your lip. As soon as you feel that absurd bump you better act quick or else the bastard will grow bigger and more nastier. They take 1-2 weeks to go away and they always seem to pick the worst times to appear.
Person 1: Dude, what is that on your lip?
Person 2: A cold sore
Person 1: Oh, I never get those
Person 2: Lucky Bastard
