Alice has just poisoned Bob's drink, and Bob is unaware of it. While talking to Alice, Bob lifts the drink to his lips, pauses, and puts the drink back down to comment on something unrelated. Alice grits her teeth, but remains patient. Bob once again lifts the drink to his lips, opens his mouth for a sip, and pauses again for yet another statement.
This is when one character's food or drink has been poisoned or otherwise tainted, so that ingesting it would prove less than healthy for them. However, due to the character's Motor Mouth, or maybe it's a room full of shiny, it takes forever for any actual drinking to occur. Usually, the person who tainted the drink will be watching the person who should be drinking. Occasionally, the drink is never consumed, because the drinker's flailing gestures have spilled the drink all over the place, or the person decides they aren't thirsty, or maybe there was an accidental switch, and the poisoner becomes the poisoned.
This can be played for comedy or drama, depending on how frustrated the poisoner gets and how ridiculous the soon-to-be-poisoned's procrastination becomes.
Compare Xylophone Gag when the stalling plays out with a tampered instrument instead. Also compare Discreet Drink Disposal and Discreet Dining Disposal when somebody tries to dodge offered food/beverage by dumping it when not watched.
- In Tiger & Bunny, Kotetsu keeps getting distracted, which frustrates Maverick to no end. He needs Kotetsu to drink the coffee to knock him out so he can mess with his memories.
- In Snow White with the Red Hair a basket full of poisoned apples is delivered to the remote forest home Shirayuki is at while she's fleeing from the setting's version of the evil queen, in this instance a spoiled prince who wanted to forcefully make the fairest woman in the kingdom his concubine. While Shirayuki and Zen consider the apples and accompanying note and ribbon to be a more subtle threat, she picks up one and stares at it while talking with Zen.

- In Deus Ex Machina, Giorno is redoing the events of Golden Wind and remembers that Abbacchio is going to offer him a teacup filled with pee. When he gets to that part, Giorno mentions that he's half-Japanese and makes up some BS about how it's very rude for a guest to begin eating or drinking before a host in Japan. It impresses the gang (well, except Abbacchio) and stalls long enough for Bruno to get back so Giorno doesn't have to drink the pee.
- Played for Laughs and subverted in The Emperor's New Groove: Kuzco is served the beverage Yzma had poisoned, but he keeps insulting her instead of drinking.

- Death Becomes Her played it for comedy, with Ernest holding a drink laced with a sedative. However, his angry rant involves many grand gestures, spilling almost all of the drink.

Then the women trying to knock him out do so by hitting him over the head with some vases.
- Indiana Jones:
"... Bad dates."
- In Raiders of the Lost Ark, Indiana Jones picks up a poisoned date but plays with it for a while before attempting to eat it. Notably, he closes his eyes and chucks the date into the air, it spins in slow motion, and is caught in mid-air inches from his mouth by his friend, Sallah. Opening his eyes wondering where the date went, he follows Sallah's gaze to a monkey — which had been eating the dates — lying dead on the floor. They share a bewildered glance and Sallah drops a line that would become immortal.
- In Indiana Jones and the Temple of Doom, Indy retrieves the ashes of Nurhaci offscreen for Lao Che, a crime lord in Shanghai, but Lao tries to stiff him on the payment (a diamond). They end up engaging in some subtle yet intense negotiating in Lao's own nightclub using a rotating piece on a table — and when Lao puts the diamond on the table, it's accompanied by a glass of poisoned wine. Indy takes it and almost takes a sip from it a few times, most notably getting bumped and inadvertently spitting it out when the lounge singer he took hostage gets up. Eventually he does drink it, though...only to be alerted that something is wrong when Lao pulls out a vial of antidote. This sets off a huge brawl which ultimately leads to the aforementioned singer getting caught up in the main plot.

- Played with during the Summation Gathering in The Footprints on the Ceiling. Ross thinks this trope is in play as Merlini spends over half a chapter not drinking his glass of vermouth. (The first murder discovered in the novel was a poisoning.) When Merlini actually takes a drink, Ross dives across the room to knock the glass from his hand. Merlini nearly hurts himself laughing — he knew the drink was safe because he knew the murderer was already dead, he'd just been too busy talking to take a sip.

- This goes at least back to Shakespeare. The end of Hamlet has a poisoned pearl being dropped into a drink for Hamlet to drink. He never really gets around to it (he's busy swordfighting) before Gertrude proposes a toast and drinks the tainted wine. For that matter, one of the swords in the swordfight is poisoned as well, and takes quite awhile to hit its intended target (and takes down another while it's at it)
