Sister Zone

When you like a boy and they come out saying that you are like a sister.

Girl: "You do so much for me. Thanks for always standing up to me."
Boy: "Yeah of course. You are like a sister to me."
Girl: **Dammit...he just sister zoned me** "Yeah. You are like a brother to me."

nightmare sister colleague

A workplace cohort who has taken it upon herself to take on the role of a nightmare sister, finding ways to endlessly embarrass, harass, prank and annoy you to the point of near-insanity.

When I wake up some mornings I find myself breaking out in a cold sweat just imagining the weird and unexpected things my nightmare sister colleague might do to me that day.

scissor sisters

A) Rather good rock group popping up everywhere in Spring 2004

B) Sexual position where two ladies slot their legs either side of each other in order that they can grind front bot-bots together. Yummy.

That new scissor sisters album is so cool.

Britney and Christina as scissor sisters.. mmmm, pass me a kleenex.
