IMSB.

Congratulations! You don't even fall within human classification! You've tested into the once-in-a-million-years [IMSB] personality. Inside the IMSB brain live two immortal warriors locked in eternal combat: one called "Let's GOOOO!" and the other called "I'm such an IDIOT!" When IMSB encounters someone they're attracted to, Warrior #1 says: Go! Ask for their number! Ask them to dinner! Say it loud! Then Warrior #2 chimes in: Why would they ever be into YOU? Going over there is just asking for humiliation! Final result: stares at the person's back until they disappear, then pulls out phone and googles "how to overcome social anxiety." IMSB isn't actually dumb -- it's just that your internal monologue is probably longer than the entire Marvel Cinematic Universe combined.
