JSYK

Just So You Know. A newer term then the old and overused FYI. JSYK is a good alternative to BTW, as when you use BTW in a sentence, people might take more offense. Usually placed at the beginning of a sentence and commonly used in texting.

ANNA: BTW, Mom, I ate all the cookies that you made.
MOM: What? I was saving those! What are you going to do next, eat the cake I made for your brother's birthday?

AARON: FYI, I ate all of the cookies you made, Mom.
MOM: Don't talk to your mother so rudely, Aaron! Go to your room!

AMELIA: JSYK, I ate all those cookies you made, Mom.

MOM: Oh, that's okay, Amelia. I can always make more.
