carving
🅁 Core Metaphor:
"Like your trucks biting concrete — but on snow, the edge bites the mountain."
🏀 Hobby threaded · Skateboarding

🎯 Kai, 19 — Chengdu

"I skate. But I'm watching snowboarding now."

Kai knows carving on concrete. But X-Games snowboard commentary hits different — same word, different world. DynaSaurus maps his skate vocabulary to snowboarding in seconds.

Chinese skaters say 卡边. Snowboarders say 压刃. DynaSaurus catches the cross-linguistic trap before Kai repeats it.

🤿 Maya, 24 — Bali

"I dive with a tank. Now I want to dive without one."

Maya is PADI certified. Free diving is the next frontier. She hits mammalian dive reflex — a term that simply doesn't exist in scuba vocabulary. DynaSaurus gives her the bridge.

Indonesian selam covers both scuba and free dive — one word, two worlds. DynaSaurus threads the explanation through physics she already knows.

intersectionality
🅁 Core Metaphor:
"Like market segmentation — a person isn't just one identity."
📚 Gender Studies 101

📚 Alex, 21 — Marketing Major

"I know market segmentation. What's intersectionality?"

Alex takes a gender studies elective. Every reading hits intersectionality. Marketing textbooks never covered it. DynaSaurus anchors it to a concept Alex already owns.

Market segmentation: a consumer can't be reduced to one demographic. Intersectionality: a person can't be reduced to one identity category. The metaphor lands.
