the art of slapping the upside of your head, usually follows after someone says or does something insanely stupid. Leroy Gethro Gibbs started this trend in NCIS to knock some sense into his team.
Also can be used as a warning before a bitch slap.
Laura gave me a gibb slap after she found out that the fall off the roof hadn't hurt me.
Girl 1: My boyfriend and I broke up last night when I bitch slapped him for checking out another girl's ass
Girl 2: You should have just gave him a gibb slap and you two would still be together.
Coined by Gibbs himself, it is short for 'Gibb's second law of relational-dynamics'
It states that:
Relationships between members in a squad will not last for long and when they do end they will tend towards the detriment of the squad as a whole and will probably involve a lot of angry paras sent over iMessage and/or Whatsapp.
Person 1: "Did you hear that Sarah and Matt broke up?"
Person 2: "Yeah, I had 374 unread messages on Whatsapp"
Person 1: "What can you do, it's just Gibb's Second Law!"
Coined by Gibbs himself, it is short for 'Gibb's First law of relational-dynamics'
It states that:
No relationship between two persons can ever remain purely platonic, it will either end with one member (usually the male) feeling friendzoned and thus ending the relationship after they lose all hope, or with the relationship becoming romantic, in which case Gibb's Second Law must apply as Gibbs is always right.
Person 1: "Whoa, Sarah and Matt are such good friends!"
Person 2: "Trust me, they're gonna be more than friends soon enough"
Person 1: "Oh yeahhhh, Gibb's First Law, lucky Matt!"
