One of the more recent trends among expecting parents are gender reveal parties. Think of a pre-baby shower where family and friends gather with the parents to be where the gender of the baby is revealed in some sort of dramatic fashion like slicing a cake, busting a pinata or popping a balloon that either contains pink or blue.
Footage below shows an expecting Mother who appears to be leaving a store while he son innocently plays with the balloon in hand....and BOOM - gender instantly revealed.
