Students have been describing a new phase in their ambiguous courtship ritual: the "define the relationship" talk. They dread it.
They hang out. The group does things together. Two people start "talking" (or are "at the talking stage"). Some kissing may happen about here. Or more. Possibly with alcohol involved. While still hanging out, and doing group things, and talking.
At some point, the couple starts to wonder if they are a couple. Often, he is enjoying the ambiguity, especially if the kissing and more is included. Usually, she will crack first. She will say, "we need to define the relationship." Then an earnest and often uncomfortable conversation follows, which, she hopes, will result in clarity.
How will she know for sure if they have moved up to boyfriend and girlfriend?
He lists her that way on Facebook.
