A combination of the words "post," "boast," and "poaching." It is a reflexive action of participating in social media culture of displaying ones personal life out of temptation to compete with their peers, while inadvertently volunteering personal information about the self and ones relatives.

person3: Man, person2's personal account of their own life is amazing!
person1: they poasted all their kids bullshit while vacating up in dat 'Cun (Cancun)
person3: Back in the day, we had to get a parent signature on a piece of paper and bring it back to class have our photo taken for the public. That poasting has to stop!
