I was speaking with a friend about going on the swings when he mentions the act of someone pushing from behind and going underneath the swinger. He called this an “Underduck” and I call it an “Underdog”. Neither of us had ever heard of the other name for it but I’m just wondering, what do you call it? Keep in mind we both grew up in Alberta, Canada…
A very casual poll regarding the existence of both terms is located here.
Keep in mind, I googled both “swing underdog” and “swing underduck” and got about 540,000 hits for underdog and 54 for underduck. But this could also include the other definition of underdog…
