Slang intensifier. If you do something like a mug, you do it particularly much, or fast, or often, depending on the word. If you say "She was runnin' like a mug," for example, you mean that she was running really fast. Some say that the phrase derives from "like a motherf___er." I don't know about that, but it's an equivalent statement, so maybe so. William Gates uses the phrase "like a mug" in one of his interviews in the 1994 masterpiece Hoop Dreams.
"I got 15 rebounds. I was jumpin' like a mug."
"You can't believe anything she told you. She was lyin' like a mug."
