It means, Strangers to Friends to Lovers to Strangers.

"From Strangers to Friends, friends into Lovers and Strangers again." It is from the song Strange by Celeste, please go listen to it. It is absolutely beautiful.
"You know how relationship goes, s-f-l-s. Nothing ever lasts."
"S-F-L-S, we are in the love part right now, so I have to ready for us being strangers again."

Shower, Shit, Shave, Have A Wank. As with "Something about Mary" its best not to go on a date with a "loaded gun" so this is the correct first date preparation...
Go to go - I still need to S. S. S. H. A. W. before my date tonight...
