j1er
A J1ER is the person who shows up to every party like they own the place. They know everyone's business and take credit for everything. They also take way too many selfies.
J1ER walked in and immediately started taking selfies with 5 different people at once.
At the party, J1ER was the only one who knew the DJ's name and asked for a song.
J1ER showed up and took over the dance floor like it was their personal stage.
