While there are many slightly different definitions of acids and bases, in this lesson we will introduce the fundamentals of acid/base chemistry. Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.
Noun[edit] grease monkey â(plural grease monkeys) (idiomatic, slang) A mechanic, often with the specific connotation of an automobile mechanic.
For example, as the article states, though the term grease monkey isn't meant to be an insult, it was when first introduced. In fact, I'll even admit that when I first heard the term a few years ago, I thought it was meant to be an insult, especially with the word monkey put in it.
