for totes ser 

For totes ser is an abbreviation for totally serious. The for is unnecessary, it simply rolls off the tongue.

Let's say you approach me with a question such as: "Jon, did you shoot that hoe?" Then I would respond "Why yes Jake... I'm for totes ser." As in I am being (for) totally serious.
