Chillin’, Homie
This meeting between the OP (the BF) and his GF’s stepdad makes us want to facepalm so hard. The meeting went like this. Mexican Stepdad: ‘Sup, dude? How’s it going?” while extending his hand for a normal handshake. BF, thinking that the stepdad is a gangster for some reason: “Chillin’, homie,” and proceeds to try and give him the best gangster handshake ever.
The handshake went as badly as you could imagine. In the end, the BF wound up grabbing his thumb and wiggling it, which probably made the stepdad super uncomfortable (we feel uncomfortable talking about it). Good going, homie.
