The act of laying toilet paper around the edge of a toilet seat, to minimise contact with said seat whilst in the act of relieving oneself. Taken from the movie 'Copycat'.
Did you see how filthy those toilets were? I had no other choice than to do the Sigourney Weaver.

Get the sigourney weaver mug.
An incredibly intense stomach ache, physically painful to the point that its victim ponders whether or not they harbor an alien inside of them.
Because I ate that greasy Chinese takeaway last night, my roommate found me on the floor in the fetal position this morning clutching my stomach. Totally a Sigourney Weaver stomach ache!
