two meter rule

to help prevent the spread of the coronavirus the 2 meter rule was introduced: stay at least 2 meters apart from anybody

which is now commonly accepted, almost jokingly at times, when people greet you smiling, whilst simultaneously keeping their distance

man: pass me that drink
women: well i can't because my arm is less than two meters long, so i'd be breaking the two meter rule
man: oh common just pass me it ffs

Manydem

Often in a political context, the term “the many not the few” is used in campaigns, focussing on the large majority of the typically underprivileged population; instead of the elite few, who often oppress them.

So, “for the manydem”, essentially means the same thing - and of course is a play on words - but referring to a subset of this population known as the mandem

Mandem 1: Hey bro that ain’t no regular graph

Mandem 2: Yeah man, it looks more like art

Mandem 1: Low that shit.......but wait it says “for the manydem” are they talking about us cuz?!

Mandem 2: well for real, we da mandem
