I like to talk with my hands (wild gesticulations and such) , find conversations in which I can use the words "hullabaloo" and "tittynope" successfully, and have a tendency to get very passionate about life.
Insert your usual drivel about enjoying new things, jogging, yoga etc. I like all that too, but apparently it's not all that original.
I randomly bro out and say "Dude" a lot. I imagine this is from playing ultimate frisbee nearly year round.
