Get the Manjina mug.Manjinders are very well known, and popular. They tend to be a bit on the annoying side. They are easily frustrated and difficult to handle. Manjinders are hairy in a baboon manner. Manjinders are cocky , but they are the ones to be counted on an bad situations. Manjinders are weird and like elephants . They are hard to resist.
