the act of semen escaping from its intended destination. most commonly happens with condoms when u bust ur load and lose firmness. allowing for semen to seep from your happy hat. Another common ordeal is when u have a real vengeful trick that pokes holes in ur happy hats. ultimately resulting in a 9-month trip down the highway from hell that last for 18+ years.
