Arm fluttering

"I've done some research, and I believe it means the person cares SO little that the last droplets of care spirit are being sucked out of their body, through their arms, and out of the tips of their fingers, and into the outer reaches of interstellar space to be lost forever. A true indicator that person doesn't give a fluff."

- Pillow in Getting Teardrop to Talk

Arm Fluttering is a common gesture used in BFDI. It is usually used to show a character's extreme excitement, panic, or anger.

The gesture went unnamed until Getting Teardrop to Talk, when Lollipop first coined the phrase. However, Pillow's research concludes that the gesture is a way of showing extreme disinterest in a topic. She claims that it allows one's "care spirit" to be sucked out of their body though their fingers and into Space. This is obviously not true, of course.

Coverage
Arm fluttering first appeared in Take the Plunge: Part 1 when Match said "…but Flower went CRAZY!"

In Getting Teardrop to Talk, Teardrop flutters her arms when she is interested in Eggy's story. She also did the gesture (off-screen) when Lollipop tried to sell her Fork Repellent, which she probably wanted considering she was stabbed with a fork earlier in the episode. Coiny does the gesture when he begs Four to bring back Pin after he disfigures her. Barf Bag also did the gesture when she got mad at Lollipop and Pillow for undermining her, and Firey also did it when talking to Loser.

In Why Would You Do This on a Swingset, Lollipop was in an argument with Barf Bag when she grabbed her arms and forced them to flutter. She used this as an excuse to change the subject.
