Hopefully UrbanDictionary can be of some help in your quest for deciding to use this awesome and so-fisticated lingo…

 Totes: An abbreviated form of ‘totally’. Used in conversation because one syllable is better than three.

And check out this great conversation between Doctors Barry and Barney, with Ph.D’s
Barry: ‘I am totes going to the party! It’s going to be immense!’ 
Barney: ‘Hells yeah!’

Helpful Sidenote: Doogie Howser loved to use this word as a professional 17-year-old medical doctor. Just goes to show that it’s definitely hip and poppin’ fresh.
