cock blockin 

Cock blockin has many definitions.

1.The most commonly used definition for cock blockin is basically the term for an act that someone does on purpose that sabotages a males attempts to have sexual relations with a prospective female. This is usually done by someone close to you and knows how to manuever such acts without appearing to have those intentions. This term can be stated by either a male or female.

2. The lesser known definition for the term cock blockin is when an amatuer dj is learning and needs to practice on other peoples equipment until they can afford to get their own, when a very experienced dj or someone who is just a control freak prevents the amatuer from being able to practice, therfore blockin the progress that could have been attained through practicing.

3. Cock blockin is also a way of describing a female who attempts to demonstrate an appearance of dominance through body language, verbal insinuations, and also chooses to ignore the other women she feels intimidated by, which prevents any form of friendship. A woman who cock blocks usually has had many unsatisfying sexual relationships and is jealous of a woman who has experienced love. She will intentionally compete for that males attention fully aware that he is attached, only as an attempt to capture the other females essence of love. This type of cock blockin is common with prostitues and strippers.
Seriously, that's cock blockin for real!!!!

Cock blockin/ cock blocking 

Similar to cop blocking, only more specific. An interference, that brings a hault to any sexual act involving a man's (or a woman's in some cases) penis. It is sometimes used even when a man (or a woman with a penis) is just talking to someone, this is a stretch but is appropriate as long as their intentions are to eventually have sex with the person they are talking to, and they have some chance. If the person they are talking to shows no interest, and one interrupts...then they are probably doing this person a favor. Either that or just adding insult to injury.
Yo we was kissin, she had her panties off and her hands all on my dick, I was just about to smash...>sigh< until John cock blockin ass "accidentally" walked in on us.

Olympic Cock blocking 

cock blocking at a level so high, that you cant believe the person that is attempting to prevent you from gettin some play is still trying. so it can only be known as the Olympic level. this person will try to pull out every excuse to prevent you from having a good time, whether boy/girl, even if it means making a bullshit excuse or story to avoid a possible score for you. these people are basically trying to play defense when they are already down by six TD's in the end of the fourth and you are guaranteed the trophy and all that shit.
the party is coming to an end and Im vibin' really good with this one chick. but some asshole is tryna get in the way of my score with this chick and i hurdled all his shit like it was the olympics. he tried to invite other people to stop me from gettin my girl, he jumped into every convo we was tryna have. this dick even tried to critisize some small stuff like the color of my shirt to make me look like a shithead. yo even tried to split a cab with me an my girl but my girl set him straight by saying she was going home with me and thats when everybody at the party knew his ass was tryna cock block at an olympic level,so it could only be described as Olympic Cock blocking.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
