To do a 'Dixon' is to shit yourself and fall in love with a chick extremely quickly. Additionally, one might also neglect spending time for his friends, instead spending all of his time with his new chick.
Dude, I'm falling in love..
Duuude, don't do a Dixon on us..
Dude I'm not..
Duuuuude, yes you are- you only met her last week and you spend every second with her. You've already introduced her to your mum for fucks sake!
Oh yeah, Well I know, but I knew this was going to happen...
