Sidewiper

Bro, do you wipe your ass from the center between you balls?

Naw bro, I'm a Sidewiper... I lift a cheek, yo.

Sidewiper 

Someone who continues to do something as they were taught even after knowing/seeing a much better method. A person who wipes their ass sideways cheek to cheek instead of up or down between the cheeks.

That guy stinks like shit, he must be a sidewiper.

Sidewinder Joseph

One of the greatest pitchers of the early 1900s. Born in Brownsville, Arkansas this hefty thick thighed left hander amassed over 342 wins in his career while striking out 2,231. Known for his infamous “sidewinding” technique, Mr. Joseph also saw success off the field as well taking home an astounding 14,532 women during his playing days. Learning to pitch from his father who was a horrible alcoholic and goat farmer, Joseph was able to use the beatings given by his father to strengthen his core thus giving him a competitive advantage. Dying of untreated Gonorrhea in 1932 Joseph’s legacy still lives on today throughout the deep southern lands of this great country.

Sideliner 

AKA: "Sideline bitches", are the large number of people who sit around in the confinement of their own little worlds, picking apart the actions and efforts of others. These sub standard human beings often do not even realize that they are indeed a bunch of do nothing, whining, over opinionated, pussies, with no personal accountability or personal experiences. They tend to form their opinions based on other's words, most often provided by the media or other sideliners, allowing them to feel like they're part of the action. They will talk until the day they die, but will never be the person who actually takes part in events that are worthy of discussion or praise.

1)Dude #1: Man, this douche bag keeps trying to holler at my girl while I'm "away on business". Telling her, "if I cared I wouldn't be leaving."
Brotha'#2: What a motha'fuckin hater.
Dude #1: Ya, he is quite the sideline bitch. I think I might have to kill him. Want to help me remove his teeth and burn the body?
Brotha' #2: Fo'sho.

2) The self proclaimed "left wing", liberal elements of the United States political scene are nothing more than a bunch of sideliners. Someone should explain to them that waving signs and chanting won't stop extremist organizations from expanding and beheading them.

3) It is not a good a idea for a sideliner to approach a United States Army Ranger with his or her bullshit. It will most likely result in them getting skull fucked.

Bulgarian Sidewinder 

A move used to passive-aggressively walk past a group of slow walking teenage girls. If you are stuck in a hall, and a group of girls is walking slowly in a wall formation, walk faster, and squeeze through them, making your annoyance known.

Tennage girls: *walking in a wall* Omg did you see Ashlee’s shorts yesterday? I am so litterally dead. I’m screaming

Person: *Bulgarian sidewinder*
