The loud farts that always come to let you know you need to take a shit. The magnitude of these farts ofter will indicate or "preview" how retched the shit will be.

When a person lets you know in advance what they plan on baking for some event or just for fun.
Duder 1: "Oh just give me a break. Cookies, cake and brownies that's what I'm gonna bake."

Duder 2: "Sweet dude! I can't wait for your grandma's funeral! Your baking preview left me craving them shits."

A dishonest, untrustworthy person's first, seemingly innocuous gesture that should have tipped you off as to their character.

Refers to any occasion when you feel a large bubble of gas "transfer" or "travel" from the upper part of your colon to a position somewhat lower down, but without actually exiting from your butt immediately. This gastronomical "heads up" can be extremely useful in allowing you to both adequately prepare for the eventual "eruption" and hopefully prevent any disasters/embarrassment from said expellation, since it not only notifies you that a sizable fart is imminent, but it also enables you to (1) judge the approximate size/intensity of the upcoming whizzpopper and thus determine whether you should hastily change locale to avoid offending others' ears/noses, and (2) predict what **type** of fart ("dry" or "wet 'n' messy") it will likely be, so that if necessary you can rush to the bathroom, shed your pants and underwear like they're on fire (if they aren't already smouldering from repeated extra-spicy-chili farts!), or take other appropriate steps/precautions to lessen your chance of soiling both yourself and anything else that your butt happens to be in close proximity to, such as a chair, mattress/bedclothes, someone else's lap, etc.
Girl, surprised out of a sound slumber by her guy's sudden alarmed flinging off of the bedclothes and hasty exiting of the bed: Where ya going, honeysnugglez?
Guy, calling back over his shoulder as he's sprinting for the bathroom: Sorry, sweet cheex --- didn't mean to startle ya like that, but I felt a major liquid-fart preview back there.
Girl, giggling: Well, you know, I did warn ya about partying till 2am at that Mexican all-you-can-eat bash --- now you're payin' for it, eh???
