وعليكم السلام,المعنى:خذ الامور ببساطه و اجلب لحياتك ببعض المتعه وستكون حياتك افضل. Peace be upon you,it means :Take it easy and have some fun in your life and you will have a nice life.

وعليكم السلام ورحمة الله وبركاته مساء النور! This used to be a very common expression in Saudi Arabia... It is structured like this Do something > something will result > something will result فرفش = Act in a fun manner تعش = you will live تنتعش = you will be refreshed There's another one which starts with طنش instead of فرفش... طنش = forget it (more like: ignore it) It would be, ignore it, you'll live and feel refreshed It's highly informal, and can be used with friends and when describing ones own personal behavior, as in, I'll act this way...

تعنى ان تعيش دائما بسعادة وفرح دون النظر الى صعوبات الحياة
