Easlick
The roommate who hides in their room like a scared little mouse. If you try to pull them out, they'll scream at you like you just stole their last chip.
You: 'Hey, wanna watch a show?' Easlick: 'No. I'm in my room. Don't bother me.'
You: 'Let's play Fortnite!' Easlick: 'I'm not playing. I'm in my room. Go away.'
You: 'We're going out!' Easlick: 'I'm not going. I'm in my room. I'm not coming out.'
