|1.||Eskimo related couch buddies|
When a set of friends have realized that they all have had some sort of sexual relations on the same couch in the past or present.
"yeah me and him always hooked up on that couch after school"
"no way I just hooked up with ___ on there the other day!"
"then I guess that makes us Eskimo related couch buddies! Considering we both had hooked up on the same couch"
