A variation of "Focus". Often used by Facebook's Delicate Flower as she immitates someone she works with who has a strong accent. Also used by the "Fuckus in Fitness" group that spun off from Delicate Flower's page.

Get the Fuckus mug.
A combination of fuck (or fuss) and ruckus. A random misspeak that occurred when a friend was telling the day care lady to call her if her kid raised a "fuckus" when she was wanting to say fuss or ruckus. It came out as fuckus and caused a very embarrassing situation, and yet in retrospect very funny. When a child is acting up, they are raising a fuckus. An extreem fit.
My son got into a bag of m&m's and then on a sugar high raised a major fuckus
