I 43(F) have been seeing my son 13(M) trying to get me and his father to say the word "Gex." What does this word mean and why does he keep saying the simple yet enigmatic sentence "Say gex."?

For starters fml, it was the middle of the night, I was just gooning on my computer until my dad entered my room to tell me to turn off the AC and saw me gripping my fucking meat and porn full screen on my 32 inch monitor, he just silently closed the door went back, after a few hours i heard him and my mom arguing about kicking me out.
Now im terrified if they actually do it
