When a female (usually an older woman, particularly a mother) wears unflattering, waist high jeans that give the buttocks a flat, unappealing look. It may sometimes entail wearing sweat pants bought from your local Walmart. Also note the buttocks may possibly look as if there is a large amount of cellulite. Either way, you don't want that.
This phenonmenon has been around since at least the 80's. It is defined as the elongation or widenty of a mother's butt when she wears jeans/pants that are too tight, too short, or too high in the waist. One does not have to be a mom to aquire mom's butt. One does also not need to be fat to aquire mom's butt. However, there is a vast cohort of Mom's Butt sporters at youth soccer games. A true mom's butt shows a panty-line that usually is uneven due to a "wedgie". Pockets are usually too small and too high on the pants, thus, creating the mom's butt shape.
Everyone can experience mom's butt. There is a make-your-own mom's butt method that you can do at home. First put on a pair of jeans. Second, pull them up as high as you can, almost to wear they cut you. Then bend over a little and look in a mirror from behind. MOM'S BUTT!
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
