It seems to me that when you've reached the stage of life where y'all's children are eligible for AARP, all y'all's grandchildren are married, and some of y'all's great-grandchildren have their own Web sites, you should find a term other than boyfriend for the guy with whom you're hooking up, hanging out, going steady, or whatever.
When you reach the age of 80, you can can stop calling y'all's partner "boyfriend", but "manfriend".
