It is a bit difficult to determine the word -- but keep in mind that 'B' at the end of a word is devoiced to a 'P' sound. The same goes for 'D' devoicing to 'T'. Thus hearing '❤❤❤❤' could thus be '❤❤❤❤' or 'krab' which both mean 'crab' in English.
❤❤❤❤ in Dutch can mean narrowly, cramped or crab. However within the context of this question crab would make the most sense.
