Wikipedia has a good article about it: https://en.wikipedia.org/wiki/Use_of_human_shields_by_Hamas
It's not a term I've seen any real evidence for. If anything the opposite is true according to the linked and Guardian article. Israel is pursuing a policy of killing suspected members of Hamas in their family home/building when they are not engaged in warfare, using dumb bombs that guarantee there will be significant civilian casualties, likely in the low to high 10's and possibly higher.
The IDF commonly uses palestinians as human shields though.
