Easlick
A roommate who lives in their room like it's their own personal tomb. If you try to get them out, they'll yell at you like you just broke their favorite toy.
You: 'Hey, wanna hang out?' Easlick: 'No. I'm in my room. I'm not coming out.'
You: 'Let's play video games!' Easlick: 'I'm not playing. I'm in my room. I'm not coming out.'
You: 'We're going to the park!' Easlick: 'I'm not going. I'm in my room. I'm not coming out.'
