Swatch means in general - to have a brief look.

Girls have been using that word lately as an expression for testing make up products. So, when someone buys some new make up, they swatch it - try it out, put on one time on their face, eyes, lips.

Usually that means, either they put some product directly on their face or they try out the colors on their wrists, hands. Then, take a photo of it and post it on blog or in Youtube video for others to see how that color stays on skin.
These are the the swatches of the Elf Beauty School Eye shadow I bought for $5.00.

I swatched almost all of these colors with a very thin base of Too Faced Shadow Insurance just so they’d stick better.

It's when MrKeego brain melts and he tried to say Switch/Swap.

Swatch is a combined word of Switch and Swap if you wanne say it fast and forgot either of the words.
