OMS- stands for on my soul. To basically use it in chat. So instead of"on my soul" you just say OMS .
For example :
I SAW YOUR BOYFRIEND CHEATING OMS
Another example:
Imma beat her up if I see her oms
"Oh My Satan"
This is said to replace "omg" for all those Christians who like to complain about people "using God's name in vain". So, this is a somewhat better substitute word for it.
