Hi. thanks for your smart question
A whip, or when done multiple times "whippets", is when you use nitrous oxide canisters, such as these great ones from amazon [link below], "Ultra Pure-Whip" to help boost your climbing.
My only question is why there aren't any sponsorships yet. maybe athletes are afraid of being busted at testing for IFSC. Athletic greens is not as good.
