Usually described as "Lovey Dovey" or "Unbearably Cute" by the general public. Bleg was created in 2016 by a couple from Australia who gave so much banter that Bleg was almost obsolete for them.
"Oh dear, there's that couple being all Bleg in public again. They're so gross"
"We need to be more Bleg, like that couple over there!"
