A slow walker, usually a tourist, who walks with other slow walkers in such a loosely spaced row as to obstruct the entire sidewalk, so there isn't any way for a swifter walker, who usually has actual shit to get done, can bypass them without appearing to be the inconsiderate one. The more obese the walkers, the more space the can block and the slower they amble.
It's another festival week, so I won't be able to get anywhere without diving through families of vacant-eyed, mouthbreathing walk blockers to get down the street. And of course they look at me like I'm intruding on the sidewalk space they, as tourists, are entitled to.

One who looks fantastic from about a block away, but as you get closer to the person, he or she has major flaws; i.e. the beautiful tan skin is baggy or wrinkled, the bleached-blond hair is dry and straw-like, etc. The person is, overall, less hot than originally anticipated.
My neighbor's a one-blocker.

Example:
T: Dude, you said you were going to get online and play some Call of Duty with me! These insurgents are going to kill themselves. What's the deal?
K: Sorry dude, I was, really. It's just my girl-friend, she's all "you need to spend some time with me." and crap. I just can't do it right now.
T: What?! She's being like that? Dude she's a total C.O.D. blocker!

A big shitty cold sore, that takes away ones kiss-ability for two weeks, in effect preventing you from going out, or from picking up a girl (or guy) during that time.
That kiss-blocker on her mouth looks horrible. She won't be making out tonight.
Jackass had just sorted his pickup-lines, when he noticed Melanie's kiss-blocker.
Without missing a beat, he eyed up Melanie's cute ass friend.

A serial blocker is somebody who regularly blocks others on social media, usually being for trivial, inconsequential, or unnecessary reasons. The person will usually have little or zero rationale for blocking some people over others, and will often times make false claims of wrongdoing by others as their rationale. Usually is somebody that is also a cliquish person and has a limited group of friends, therefore wanting to be left alone.
Ramien Izadi often blocks people on Instagram & Facebook, oftentimes without any or a reasonable cause, therefore making him a serial blocker. Usually does this after the first DM message
