Small signs that someone plays league?

What are some irl signs that someone plays league? There's basic gamer lingo like tanky, gank, tilted, "that's OP", and "ADC went on-hit Varus, parents must be related"

One time in college my friend corrected a spelling mistake I made, and I accidentally muttered "are you even human? NPC degen freak" and then I had to explain the time I AFK'd as 10/0 Draven because my Nautilus support panned his camera to a different lane.

A few years ago I cut off my family so I could focus on learning Yasuo/Yone botlane haha. Got me from Bronze 4 to Bronze 3 (worth). We're still close, although I haven't spoken to them in years.

Anyway haha, what are the signs that you play league?
