Maud Pie is Pinkie Pie's older sister in My Little Pony: Friendship is Magic, introduced in the season four episode 'Maud Pie' in 2014. Voiced by Ingrid Nilson, she is a deadpan geology student whose love of rocks and flat delivery made her an instant fan favourite. Her dry one-liners became a steady source of reaction memes in the brony community, and clips of her monotone observations circulate on TikTok and YouTube as shorthand for unimpressed, nerdy humour. The 'sedimentary' moment endures because deadpan geology jokes never go stale.
About this sound
Maud Pie's deadpan 'Hmmm. Sedimentary.' line from My Little Pony: Friendship is Magic, a dry sound effect for geology jokes and deadpan reactions.
Maud Pie delivers this line in her trademark flat monotone, the bored geology student of a sister who can identify any rock at a glance. The clip opens with a low, thoughtful 'hmmm' that drags just long enough to suggest deep geological consideration, then lands on the single word 'sedimentary' with total, unshakeable certainty. There is no excitement, no joke setup, no punchline — just pure deadpan confidence. That dryness is exactly why it works: it turns any dull object, boring opinion or painfully obvious observation into a moment of unintentional comedy, and its flat delivery makes it endlessly quotable.
