Occurs when a man simultaneously shits and cums during ejaculation either alone or with a sexual partner.

When I have sex with her, it's so good that it makes me shum!

Shum 

You can say "shum" after a person coughs to acknowledge that you are not bothered by the cough, and that you hope they are okay.

It is pronounced: sh-UM

It is inspired by the calming "uhm" sound that is more soothing to others when they are coughing

John: *coughs*
Henri: Shum to acknowledge John's cough

A Shum is a person who buys new versions of phones as soon as they come out and disregard their perfectly fine old versions of the phone.... Usually people in their late teens and 20's, who want to look "cool" by having the newest versions of phones)

That Shum Dave just spent $300.00 on the new Galaxy phone that came out yesterday, although his old Galaxy still works just fine.
