Nicotine is one of the most addicting drugs, so lord knows how people manage to quit. I used to drink every day for about 2 years straight, currently I drink 5 days a week. I'm quite consistent in that I drink approximately 5 pints of Beer worth per drinking day.
With how much I mentally rely on drinking to enjoy life and relieve stress I'd never judge someone for being a smoker. I can't see myself ever being teetotal.
I never knew Gal smoked, but googling it shows she used to and decided to quit. With these pictures being a few days old it seems she's relapsed. When you're hooked it's a bitch to quit.
Is English your first language? I'm not trying to be insulting but this really is self explanatory unless you don't know the slang, and English is difficult enough to learn without knowing the slang as well. Hell, half the people in the U.S. can't really speak English, but I digress..
"Poke" "poking", or "getting poked" is slang for sex. Lois Griffin (a bad girl herself) was giving "advice" to her son about finding a "willing" girl sexually.
In the old days, it would often be assumed (right or wrong) that a girl who smoked, drank, dressed provocatively etc. would also likely be promiscuous as well.
Well, that's it then! She's lost any chance with me! Even if she went down on both knees and begged me! I'd be saying 'Sorry, Miss world famous movie star/former Miss Israel/Wonder Woman - you smoke!'
