A lot of people get these concepts mixed up and use them interchangeably. They are not identical. Here are two of my old posts about clarifying:
Teasing vs. CF vs. Negging - this is clarification
the official party line of TMM definitely, and probably of VA as well, is that a neg is a false disqualifier. They make the girl think yo uare NOT pursuing her.
TEASING AND COCKY FUNNY ARE FLIRTING. Everyone who isn't a social retard knows that they are flirting (albeit competent flirting). A neg, on the other hand, is an FDQ, ONLY.
Teasing is an ioi and iod wrapped into one. That's why if you tease too early you get bad reactions. They are a way of AMPLIFYING some sort of initial attraction, because once she is attracted, you can throw iois and hit on her. But if she's not even remotely attracted and you try to tease her she thinks "wtf this loser is trying to tease me? i'm cooler than him, what a fucking loser wtf."
A neg is a FALSE DISQUALIFIER, ONLY. ONLY ONLY ONLY. If we are going to make pickup into a science we have to try to be as correct as possible.Cocky funny (depending on how its used; and it should generally be used as a playful form of teasing, not as an asshole-ish move) is a DHV and an IOI. It is competent flirting - like teasing. If you call a girl a nerd or a dork or you hipcheck her you are
1) demonstrating that you are fine just having a fun time and you're not taking the interaction too stiffly and you're a fun guy (DHV) but at the same time 2) it is VERY clear to a person that teasing is an ioi. You don't tease a bum on the streets. A girl doesn't slap you on the arm if she actually is disinterested in you (except for fake ioi's but that's totally differenT).
it is NOT an FDQ. If you call a girl a nerd she KNOWS you are teasing her - she knows you are flirting with her - it's you showing her you like her and can have fun with her but you're doing it in a competent manner. That's why cocky funny sometimes doesn't work immediately off the bat because you haven't established the unreactiveness and flipped the value switch that's required before you can really nail it and the girls LET you establish that frame where you're cooler than them/teasing them
