bolt on boy

A "bolt on boy" is a mechanic in someway. He can bolt things on but doesn't truly know what the parts do and how they work. You can almost relate a bolt on boy to the local oil change technician. There is a difference of a performance shop and a racing shop. Performance shops buy parts from online or magazines and install them and that's it. A race shop will search for parts that suit a build, determine what parts are needed for the type of performance, and understand the fundamentals of performance.
Customer: What cam should I get?

Owed Shop: Well we have stage 1, 2, and 3 cams.

Customer: That doesn't tell me anything. What do those numbers mean?
Perf Shop: The stage 3 is the fastest
Customer: But, why?
Perf Shop: Its our custom grind
Customer: What are the specs?
Perf Shop: I'll have to get you those later.
Customer: Are you just a bolt on boy?
Perf Shop: Well, yes we simply just install parts and have never specd a cam nor know exactly how they work.

Customer: Thanks for being honest!

bolt-ons

1. Slang term for a pair of breast implants that look unnatural, rock-hard and "bolted" onto their owner's chest much like the stiff, painful looking screws that were bolted on to the side of Frankenstein's neck in the classic horror film. This "bolted-on" look typically happens because of what is called capsular contraction. Capsular contraction is when scar tissue forms in the chest cavity and tightens around the implant(s), making the breast(s) hard and unnatural looking. The "bolted-on" look can also occur when extremely large breast implants are inserted into someone without enough fatty tissue in the breast area. "Bolt-ons" do not look natural. All bad boob jobs where it's obvious that the person has implants can be referred to as "bolt-ons".

2. A messed up boob job.

3. Cause for a malpractice suit.
"That chick's boob job doesn't look so good. It looks like she's got two rocks in her shirt."
"Yeah, those are a serious pair of bolt-ons."
