Three answers that immediately come to mind though there are of coarse many more meanings. One is will you lightly tap me on the shoulder when so and so appears. The other is, would you tap (Borrow off) me for 10 dollars if you were in need?. Another is, would you tap into my pocket to steal my money?
Do you mean 'where did tap dance originate?' On slave ships, slaves would have pennies on their feet and they would dance around making the tapping noises.

Tap can be a verb or a noun. As a verb, "to tap" means to touch lightly. For example you might "tap someone on the back" in order to get their attention. In Portuguese, the closest I can think of is bater de leve. Similarly, as a noun, a "tap" can mean a light touch (uma tapinha, uma palmadinha). However, "tap" can also mean a water faucet (uma torneira). The phrase "on tap" (as in "What kinds of beer do you have on tap?") is used to mean beers that come out of a dispenser rather than a bottle (similar to um chope or uma cerveja de barril).
