Another way of saying "pissing on your own chips", "making things harder for yourself", or "shooting yourself in the foot". If you've shagged yourself silly, you've really messed things up for yourself and created a total disaster which could have been avoided had you stopped to think. This phrase takes a nod to the act of inbreeding.
Dear Tory Twat, you're absolutely shagging yourself silly by planning to build over 7000 houses on a floodplain.

The polite way of telling someone they're a dumb ass without letting them know you're thinking they have recently acted or spoke without using even an nth of thought/brain activity.
Act: Your best friend insistently waving at your mom as you drive past her in the Walmart parking lot while skipping school.
BFF: Look! It's your mom. (Waving and yelling, "Hey Mrs. Connor")
You: Yeah but we are supposed to be in gym class right now, Silly!

a phrase used by only and ONLY elites. I’m sorry to say that if you are above the age of 18 and use this phrase then you are not to use the phrase silly goose but instead the phrase over-date goose. also if your initials are A.K, A.M or KK then lots of love from sushi.
