Swedish blackhole 

when the partner licks their partners asshole. and after they have some Sh*t on there mouth/tongue they make out hardcore until the partners mouth is as brown as the black hole licker's mouth.

Last night Jenny wanted to do a Swedish blackhole, but i don't really like to do that. Then she threatened me with no sex; so we did it.

Supermassive blackhole 

A very massive blackhole. A supermassive blackhole is larger than a mega-blackhole, but smaller than a hyper-supermassive, (ie. hypermassive) blackhole.

'Two mega-blackholes merged to form one so massive that it became a supermassive blackhole, but even that's nothing compared to the size of a hypermassive blackhole.'

(Please read my definition of a mega & hypermassive blackhole for more information).
