Younger sibling

A little pest who likes to burst into your room while your doing homework, or playing on your phone. They like to hit you, then like a little bitch, they tell your parents when you hit back. In other words...they are annoying. They are so annoying they make you feel like banging your head against the wall so hard you lose all your brain cells.

You: *on your phone*

Younger sibling: *bursting into your room and runs up to you* Hey!

You: Go away.

Younger sibling: No! *Slaps*

You: *Slaps back*

Younger sibling: ....MOooOOoOoM *ugly sobs*

You: GODDAMNIT *bangs head against the wall*

Sibdog

A cool guy who teaches kids life lessons like how to style their hair and wear the best clothes. He likes to speed walk everywhere shaking his shakira hips. His bald spot is shinier than anyone’s future.

You sibdog taught me how to say ‘tickaroo’ today. Man he’s such a cool dude.
