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.

- 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.

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.
"... Bad dates."
