1869, Eng. dialect jerry "bad, defective," a pejorative use of the male nickname Jerry (a popular form of Jeremy), or from naut. slang jury "temporary," which came to be used of all sorts of makeshift and inferior objects.

Note: "Jury Rigged" is a temporary solution done with materials at hand (and can be considered clever), while "Jerry Rigged" (or "Jerry Built") is a poorly made permanent construction, and has no positive connotations.

In reference to a person having a weird shaped body.

fully built

The term Fully Built has been in the Gear head vernacular sense the mid 60s and implies something has been improved for high performance, or to withstand harsh use. Important to note: Although this would suggest something could be fullerly built, the adverb "fully" does not imply completion, or reaching a point of "maximum potential". Ultimately a more accurate term might be "modified within my budget, and skill, but I'm trying ot downplay there's room for more improvement." Fully Built now has a more universal application, but traditionally was used in hotrod car culture. Though also used in the import tuner community, it's often meant as derogatory eg. "That boy's snap on body kit is fully built hella fresh."

A man who pretends to be tough but knows he is actually soft as a faggot on the inside

A word used by people who have little or no experience with engines to attempt to describe how much work has been done to their motor. It usually implies they have done all the work possible to their motor and it is now at its maximum potential. Their credentials usually include having watched one or more of the Fast and Furious movies, several times. Although automotive engineers are constantly "building" and rebuilding their engines to improve performance, the people who use the term "fully built" feel their motor has reached its maximum potential after swapping out their cam gear with an awesome looking blue one they saw in Modified Mag. Additionally, the people who use this term will often detail all of the modifications (carefully noting the brand name) to their car even though all you asked them was: "What do you drive?"
