The one that sticks in my craw is "ofc," especially when it's buried in a wall of text written by someone evidently capable of typing lots of characters in one sitting. I have deduced that it means "of course," but of course since that expression could of course be sprinkled almost anywhere in a sentence without changing its meaning much, it's of course hard to be sure.
