Milkshake

At times, I use the term 'Milkshake' to refer to someone that is decrepedly old, please do not ask why as I am not even sure myself. The wife has been working longer hours this past week and as a result is feeling worn out. On the way to bed the other night night, the following interaction occurred:
Wife "I feel like a milkshake."
Me "Do you mean old, or 'My milkshake brings all the boys to the yard'?"
Apparently the wife was not familiar with the song and laughed hysterically. She still does not believe me that this is an actual song. Boy, talk about old, sheesh!
