significant sasquatch 

The feral countenanced beloved of a friend who, due to body or facial hair, appears more sasquatch than human.

Ex. 1: Though Jen loved Mike, she was certain that her friends perceived him only as her significant sasquatch.

Ex. 2: I have it on authority of an expert that the perfect gift for my significant sasquatch is a pig ear.

significant other 

Your mate, spouse, husband, wife, boyfriend, girlfriend, steady and/or lover. Used when you don't want to be too specific, or when the details are nobody's business.

Why's Roger always talking about his significant other? Why don't he just say girlfriend?

Because his "girlfriend" is a guy named Bruce.

statistically significant other 

A significant other whose status is not created by a agreed-upon relationship status but by how much time is spent with them. Could also be considered a behavioral significant other.

Combination of "statistically significant" and "significant other."

Since he spent twice as much time with Karen as with any of the other girls he was dating, his friends called Karen his statistically significant other.
