My Grandma was Southern born and raised, so a lot of Southern Dialect , sayings and nuances were little lessons throughout my life. One of those sayings that I favored is " You're getting besides yourself"- My grandma would say this to me anytime she felt I was trying to "show off", "Act up" or get "too cutesy". It was a soft way of saying, "get back in line", or "get yourself together", "humbly thyself". It is usually used by someone elder or maternal/paternal, is helpful and surely is an expression of love!
A modern phrase invented by a millennial of telling somebody to be humble and taking a crystal clear look at themselves before passing judgement and/or being critical towards others.
"Maybe you should sit back down and re-evaluate your thoughts, be humble... and get beside yourself."
Fogey/fogy /fougi/ sl. (early 18C+, orig. Scot) old-fashioned, stuck-in-the mud.
Person with old fashioned ideas which he is unwilling to change: Come to the disco and stop being such an old fogey!
You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine.

You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
