I mean, I mean --- babySITTER. Yeah... righhhhht. :P
Okay, okay --- if you insist, it means a "hot young juicy/curvy thing" who supposedly just goes to people's homes to watch kids in their parents' absence, but who in reality partakes of da assorted "sinful delights" of finding out what da household's wife/girlfriend gets to experience --- i.e., "making babies" by "sitting" on da lap of da daddy of da house --- i.e., riding him reverse-cowgirl-style --- whenever he sneaks back home to gleefully sample said "forbidden fresh fruit" while his significant other is otherwise occupied for a sufficient period of time.
Hiring a babysinner may indeed be great for "getting some on da side" --- i.e., being permitted access to a second delectable vagina besides da one dat you'd previously dallied wif and consequently knocked up your children's mama --- but you might then hafta shell out even more funds for a "second-generation babysitter" --- i.e., someone to watch da offspring of da "original" paying-her-way-through-college hottie --- if you end up getting HER pregnant, as well.
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.
