Similar to Halo, where you first get any type of multi-kill, ie: double, tripple... then on to overkill. To achieve this you must be doing more than two tasks of any sort because less that three is but mere multitasking.

A Bloomer is someone with a bright outlook on life who is optimistic in nature. Bloomer's frolic in every opportunity to be happy and try to make the most out of life. The opposite of a Bloomer is a Doomer. The term Bloomer originated specifically as a counter to the Doomer on sites especially like 4Chan.
