istg
Rising🎒High SchoolDefinition
Abbreviation for 'I swear to God.' Used for emphasis, frustration, or to stress that you're being completely serious. Stronger than 'fr' (for real), it's the nuclear option of sincerity. Often used when annoyed: 'istg if he does that one more time...'
Translation for Parents
It means 'I swear to God.' Your kid is either very serious about something or very annoyed. If they text 'istg I'm going to scream,' they're frustrated. It's the texting equivalent of gritting your teeth.
Examples
“istg if she cancels on me again”
“I swear to God, if she cancels on me again (I will be very upset)”
“this is the best song istg”
“I swear to God, this is the best song (I'm being completely serious)”
Cringe Score
Your kid will cringe
A parent texting 'istg' would be like hearing your dentist use slang. Technically correct, deeply unsettling. Proceed only if you have maximum confidence.
