I majjin
You say 'I majjin' when you think someone's guess is probably right, but you're too lazy to use the full version.
'You think the dog is gonna bark again?' 'I majjin.'
'You say the teacher is going to give us extra homework?' 'I majjin.'
'You think the kid in front of you is going to ask a stupid question?' 'I majjin.'
