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 soothing to others when they are coughing

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

Shumming

The act of shitting and cumming at the same time. (V.) (shummed, shum)

I was perched on top the toilet seat and I couldn’t handle how hot the girl I just fuck was, that I shummed myself.

I saw that hot girl I fucked last night and kept denying how I felt for her. All that anxiety and guilt had me shumming.
