sister-kisser 

In a game a very close tie. A hard fought game that ends in a tie.

The Redskins and the Rams had an up-down game and it ended 27-27 in a real sister-kisser!

sister kisser

A woman who is bi sexual, and kisses her twin sister.

Jess Origliasso, from The Veronicas, kisses her twin sister Lisa Origliasso.

You see her at a concert and you yell.

"Sister kisser!"

Six Fingered Sister Kisser 

A Six Fingered Sister Kisser is someone from an area/town/village reputed to have high incidence of incestual activities. Like the village in Deliverance.

I don’t suppose Lockdown will bother anyone in Wiltshire given that the gene pool is shallower than a municipal pool foot bath, they’re all a bunch of Six Fingered Sister Kissers

Ya sister kissed ya 

When you want to imply that ones sister is incestuous with the act of a kiss hence "kissed ya"

(Extra point if the person you say that to is female that makes them gay abd incestuous)

Sharen: yo ur mum gay
Dave: ya sister kissed ya
Sharen:implodes into a thousand southern pieces
