Gay

When the character of a person or situation is laughablly and or disappointed off the mark.

Getting home after working all day at your sakes job.
A: "How was work?"
B: "Pretty gay. No one hardly came in and I barely sold anything. Pretty much a waste of a day."

When seeing a group of incredibly trendy people being sat two tables away from you, where the first thing they do is take selfies with their sunglasses on.

A: "Thats pretty gay."
