A few times recently I thought I heard “tokidoki suru” in anime I’ve been watching. From the context the meaning seemed to be “make your heart race” or “pounding heart” (someone’s reacting to being kissed!) Am I misshearing this? I thought tokidoki meant “sometimes” and I can’t find this usage in the dictionary (nor something that sounds similar). My listening skills are crap so most likely something else but can’t work out what.
