I was bored at this party, and didn't feel like getting up from my chair so I decided to engage in sitcing.

bench sitting 

Leisure activity unique to University of Mary Washington students where one or more students observe the activities and/or listen to the conversations of others while sitting on a campus walk bench. It is common for those participating in bench sitting to point and laugh at those whom they are observing. Bench sitting can also be used to observe UMW squirrels.

Not to be confused with "sitting on a bench."

"Two UMW students were bench sitting and watched as a girl nearly walked into a trash can. They pointed and laughed at her."
