#when laughing my first instinct is to bodily crash into my twin or headbutt him as hard as i can

[mumscarian]

i think that when grian laughs really hard he hits things with his wings. like not just flapping and knocking things off shelves (though he does that too), but he like slams his wings into mumbo's back, or he just fucking decks scar with his wing, completely knocking him over. he just cant fucking control himself he has to Hit Someone
