Yup especially when forced walking behind them and the girl is all over the dude.
Was walking in my Schweden Trip and there was this Chadlite with his Stacy girlfriend and the chick was a total JB, God I was walking 5m behind them and she smelled like Melone and Honey. And she was so cheerful, full of life, dude was no different, they always looked behind and looked at me whether I am stalking them and then ran ahead, no idea I might have given them Serial Killer vibes like I always do - I mean I am diagnosed with ADHD and APS, so I have to accept people may get that vibe from me.
I can understand guys like the Zodiac Killer, dude probably saw how living and sex driven young Student couples were and just took it out of them because he never got any when he was in his teens and 20s.
Bro probably studied all kinds of science and came up the hardest to decode cryptographic ciphers ever, meanwhile Normies were laughting about him and Stacy was getting dicked down in the next dorm were he lived.
The reason they never got that guy was because he was a total shut in and his obsession with killing young people was not because he wanted to gain sex from their corpses but as revenge for not getting sex from their living bodies.
Never left DNA or a clear hint of his identity - just a social shut in guy. 100% he was Sub5 Hikikomori.
