The shape of a womans tits when she has used a push up bra to lift her saggy deflated tits so high that it gives the look of a bare shelf, empty shelf or mantlepiece

You can always spot them because the top of the shelf is flat as opposed to rounded. A genuine full pair of tits would have a rounded top
What's with the bare shelf? Just let them sag and be proud of them. You ain't fooling anyone darling, there's no shame in being a punctured princess

Lonnie and his grandmother were having a heart-to-heart discussion about something weighing heavy on Lonnie's heart. He told his grandmother, "Grammy, this shelf-life is driving me crazy. I'm masturbating like at least four times a day.....and I'm married. I've went a long time without any sex and I got to have some physical attention, y'know?" His grandmother sat there and let her grandson finish then snapped sweetly to him, "Fuck you, grandson, you done'n had more than enough pussy in this life than you deserve. I don't want to hear your fuckin' bullshit. I've been told first-hand by some that know. You don't get down in the pussy, you don't grind in the pussy, you don't take care of the pussy cause you're just out for yourself. Mutha-fucka, now Nikki, there's the muthafucka that could put a hurtin' on all these fast-ass girls you've been fucking and 'in love' with. That young man could square all that pussy away.....he just ain't got that silver forked tongue as you do or your connections. But I'll tell you this much, Casanova, and you can believe this in your ol greedy heart......That boy, to please your girl, wouldn't think twice about taking what tongue he did have and shoving it up her ass while they be locked in a full-on sixty-nine position.....I could almost guarantee you he'd put in all the work it would take till he got girl flailing her limbs, screaming his name, and coming all over his cock. Believe that shit......and grandson......get the fuck off my porch"!!!

The amount of time for which a meme is considered "spicy", or in other terms, trending. Based on the amount of time something will last before it decomposes, but with regards to memes.

Memes have varying shelf lives, lasting from a few days to perhaps even a few months, depending in its spice factor.

If a meme goes beyond this point, it is considered dead. Although they may undergo impromptu resurrection (lasting a week at the most), all memes will reach their graveyard and respective gravestones and cannot return to the internet shelf.

The shelf life of a meme is not entirely accurate or precise. Memes can be shoved off the shelf faster than the shelf life predicts, thereby accelerating it far beyond expected through use of external factors. For example, if Weird Al parodies it, or Facebook user (particularly Facebook moms) post it to the general public, then the meme dies faster and the shelf life is decreased exponentially. This is mostly unpredictable.

Shelf life is considered the best way to judge the lasting effects of memes (good or bad).

Person 1: "Hey you heard about that new Ugandan Knuckles meme? It's everywhere on VR Chat!
Person 2: "Nah it's a January meme, automatically making it terrible. It will only have a shelf life of about two weeks. At the very least, it won't survive this month."
