A quirky character from Charlies Angels played by Tom Green.

An extremely well groomed male with an average size male penis. The Chad is 6’4, has a six pack, is extremely well mannered and respectful, and is really good at soccer. He has a vision impairment, ticklish balls, and a lust for travel. If you ever come across The Chad, count your lucky stars - cause there’s only one out there.

The leader of a well organized cult, often associated closely with binge drinking promiscuity and sodomy. Often viewed as an Legend through out the national guard. Though many out side of the military have had heard tales of his exploits.

Starting the discussion about lunch plans with your coworkers, working to influence the destination and then dropping out at the last minute because you never intended to go.

The region between the balls and the arse-hole; can be an erogenous zone for some.

Girl: I was fingering that part between his balls and his arse and there was shit there.
Everyone listening remained silent but later laughed among themselves:
'Eww! He had a shitty chad.'

When you measure your dick, you don't start at the arse-hole and include the chad; you risk getting shit on your measuring tape.

1. Residue of faecal matter; usually situated between arse cheeks after incomplete wiping and can spread to balls.

The smell of chad emanates further and becomes more putrid the riper it gets; annoying all those in close proximity, while the chaded person is often oblivious to their wafting odour. Left unattended the chad will become skid marks.

2. In reference to the male anatomy, it is the space between the anus and the scrotal sac.

The etymology is uncertain as to which definition came first and it's likely the term bifurcated into both definitions after those with chad on their chad created the ambiguity.

i.e. One person telling another the smell of his chad was verging on offensive. Some of those overhearing the complaint went away assuming chad to mean the first definition above, while others assumed it was the second definition.

Differentiation between the two is determined by how chad is used in a sentence.

The girl's first sentence below is rather ambiguous, while it's obvious the guy is referring to his itchy chad (anatomy).

The guy's last sentence below uses both definitions to beautiful effect, respectively.

Both definitions spread like wildfire equally and preference of one definition over the other can be regional.

Globally, most places accept both definitions and the local translation of the English name Chad, all in lower case, is used in many instances. i.e. the term is tsjaad in Dutch, čad in Croatian, csád in Hungarian, etc.

In reference to the male anatomy, it is the space between the anus and the scrotal sac.
