I've heard of individual men's chapters making the pledges wear the pins ALL the time. So when the pledges are bathing or showering, they either hold it in their teeth, or they get an ear pierced and stick the pledge pin in there, until they get clothed again.
The holding in their teeth could be considered hazing, considering the choking hazard.
