one or more couples who hang around with each other and make out. ALL THE TIME. This is partly because everyone else is so fed up their making out in their presence and making everyone else feel akward that they have banished them to forever hang out with other losers who have nothing better to do then make out.
look out! here come the cling ons! there so fucking annoying, they were cool when they were single!

Relatives who hang around waiting for the rich older person to die so they can get first dibs on what was left behind.

They never showed any interest or care in this relative until the later years so *hopefully* they'll be left money after they pass away.

At one point throughout their pathetic lives, they told a rich, aging relative how much they love their fine china, silverware collection etc.

At family gatherings, they will show up half an hour early and leave a half an hour late so they:
a) get as much free food as possible
b) get as much free booze as possible
c) appear to be the most loving relative EVER
I'm not going to Aunt Ella's 80th birthday party until after the cling ons have left.
