Money on Grundy and Stevo being single forever with that attitude.
This rating system you have for women on a 1 to 10 scale probably doesn't help, I can imagine you going for a night out:
Stevo's mate: Hey, see that girl over there?
Stevo: Yeah, the bint in yellow dress?
Stevo's mate: Yeah, her.. She's clearly a 4 right?
Stevo: Yeah, I guess so.. Maybe a 3 (chortle)
Stevo's mate: (chrotle) Well look at the bloke she's with, clearly at least a 6
Stevo: ahh yeah, that bloke is clearly a 6
Stevo's mate: See the theory is true, women are greedy, shallow, fickle and just downright gold diggers
Stevo: Yeah, I hate women........
Stevo: .... Do you want to kill some?
And I reckon you can replace 'Stevo's mate' with Grundy.
Honestly, you two sound like you're going to end up serial killing women.
