this laugh/chuckle she does

i tried searching if anyone posted ab this before but maybe i’m not using the right words LOL bc idk how to describe it. i noticed when i watched wicked, ariana would constantly do this little laugh/chuckle that she also did in this award speech. it’s honestly so annoying, i swear she did it 20 times in the movie and it felt sooo repetitive. i don’t really go out my way to watch interviews of her lately, but from what i’ve seen i feel like she’s doing this so much now and i don’t remember this previously. does it peeve anyone else because it just feels so forced to me 😭 also, i never seen the full musical for wicked. is this something glinda did, or is it an audrey thing? or maybe just something she gave glinda’s character and is continuing it now off set? wondering where she picked it up from or if she always did this bc i do not remember it lol
