Meaning "Sorry to bother you"
a sarcastic remark when you ask somebody to do something for you when you need a favor and they are too busy or to stupid to realize you are really needing their help. Stating that THEIR problems are far more
important than yours and
don't want to be
inconvenienced.
For example, let's say you are filling out an
application somewhere and you need a pen and you ask one of the clerks to barrow a pen and they reply back "Sorry, i don't wear pins" - "STBY...."
OR
"Hey mom, i need to be
dropped off at school early, do you care to take me to school about 15 minutes early?"
and she responds "No, i have to
walk the dog during that time." "..... STBY"
