✨ NAME ✨

rvt_stop_rnr_timer — stop an rnr timer 🔥 (that's it. that's the whole job. and she does it flawlessly.)

literally one parameter, returns void, no drama, no surprises. main character energy fr 💅

👑 DESCRIPTION 👑

So the vibe is: this function stops an rnr timer and returns if the timer had been pending 😭 like, it handles the "was it even on?" question for you, no cap. you don't gotta check, you don't gotta worry — she just does the stop and tells you whether the thing was actually pending. iconic behaviour, honestly. ⭐

ngl the original page keeps it to one sentence and honestly? respect. she said what she said. 💀
