A tight pimp is someone who is just a smooth operator. A tight pimp has got his pimp all together, operating succinctly with other parts of his game: flow, mojo, clothes, limp, etc.
"Oh that dude Kyle, yeah he be a real tight pimp."
"Mike, you know what? You be a bombass tight pimp daddy."
Someone who is both "tight" and a pimp. A term reserved for only the most bad ass of people, "tight pimp" is not a term to be used liberally. As of now, there are only a few tight pimps in the world. The term originated in Iowa City, IA but has spread rapidly to many parts of the country and its use has grown substantially. Adjectives may be added in between the two words to be more descriptive...see examples.
"Oh you be a tight pimp."
"Who is the artist of that mash-up?" "I don't know, but he's a tight pimp."
"You're such fucking tight ass pimp daddy"
