jackwacker

A person who sucks at life. They are incapable of performing basic and simple daily tasks (with the exception of masturbation).

You have your left turn signal on and are clearly trying to merge into the left lane; instead of slowing down to allow you to change lanes, the Jackwacker behind you speeds up to block your access. This guy is a complete Jackwacker; he sucks at life.

jacknickulous

A ridiculous way of saying ridiculous. Used to accentuate the utter ridiculousness of that to which you refer. During the holiday season, this may be replaced by saintnickulous.

The way Grandma Esther butters her saltines is utterly jacknickulous.
