When your son tells you he volunteered to go back to Syria for 9 months-after spending over $4 grand at strip clubs in 2 days
I was gobsmacked by her stupidity

A stupid word that was made up whilst playing a game of "Catchphrase". The contestant was adamant it was a word, the quiz-master didn't think so and said no. The contestant then went into a massive sulk over it and still believes it is a word to this day.
You're a gobsmacker

To be kissed without having a say in the matter.
Did you hear Peter gobsmacked me last night? The only was he was ever going to get his lips on me.

Similar to a lemon party, this sexual act involved older and younger people, however it is an elderly lady with largely saggy boobs that is getting her 'gobs smacked' by a younger male.

Much like a kitten plays with a yarn of wool, batting it around in fascination, the young male smacks the old bat's boobs however he likes
It is also when an old lady wants to get a bit frisky and use her saggy boobs to smack a young male's gob or other parts of his body.
Male: Dude last night an old lady gobsmacked me, it was so good!

Old lady: Oh darling you wouldn't believe how well that 20 year old gobsmacked me last night, it was delightful!
