• Gon and Killua are always so competitive about who's taller. Every time they go to Gon's house, they make Mito Mark their heights on the doorframe. So now, Gon's house just has a door frame dedicated to Gon and Killua's heights
• Gon and Killua like to run around the forest and name every animal they run into
• When Killua is nervous that Gon is gonna run off and do something stupid, he grabs onto his shirt/jacket and won't let go until he feels Gon has calmed down
• They both suck ass at driving but Killua thinks he's amazing
• Killua, no matter how long they've been friends or whatever, always blushes so furiously and just so nervous whenever Gon hugs/touches him
• They absolutely love star gazing and naming constellations after themselves, each other, big events they went through, other exam members, etc
• They have a secret handshake and probably a secret language too
• Gon makes them go on camping trips all the time. Killua lowkey hates them but likes spending time with him and they always end up having fun so he goes anyways
• They don't even need to speak to know what the other one is thinking
• Killua got his ear pierced for the first time and Gon absolutely loses his mind he thinks it's so cool and Killua is too. Gon gets his ear pierced eventually too
• Whenever they're in serious situations, if they make eye contact- it's all over. They both erupt into laughter and it's so inappropriate but so funny
• Killua shocks Gon when he's being stupid or when he's wrong (like super light shocks not harmful ones)
