fwl
that friend that you've clearly had more than just friendship with, and although there's a mutual underlying love and you both secretly are planning a happily-ever-after with each other, for whatever reason must remain a friendship.
todd: hey dude, who are you bringing to the wedding?

manuel: my fwb, bro. sally's got my back

todd: don't lie to yourself bro, sally's your fwl. it's so obvious there's more going on than just benefits there
