@”Kapitán Denis” no they didnt, when its this huge you would never call it pipik.
in all seriousness my dad added -ik on to everything when I was a kid, he would say stuff like dont forget your backpackik or eat your foodik etc. In my house we spoke mostly english but some words we only used in slovak, not the english ones. For example we never said dust pan in my house but lopata or lopatka same with papuce or papucky. Slippers was never mentioned, I learned those words in school.
