Actually the word shvigger was chosen cos it rhymes with trigger…
Yes, many mils do unfortunately tell their kids what to do the whole time, not differentiating between before you got married and after. You are still their little child no matter how old you are, no matter how many kids you have ??? ??? ???. This is where the mil jokes come in.
Eg when she gives you ‘advice’ on how to bring up your kids, just tell her that you dont need advice from her cos you’re married to one of her kids and, believe me, you’ve noticed much room for improvement!
Or yakov miller’s: you open your front door to find your mil standing there. ‘What are you doing here?’ you ask. She replies ‘I’ve come to stay with you’. ‘How long for?’ you ask with dread. ‘Its up to you’ she says. ‘Oh’ you reply, ‘so you’re not even staying for a coffee??’
