different people prefer different spellings i myself prefer hippie its just whatever you want especially because it is just another label like goth or emo
its hippie....hippy i dont think is even a real word.....depends on the person i guess....hippie looks right to me.....
i think hippie looks better, but i use both, like i just type and whichever way i decide to type comes out, it's all got the same meaning, it's like colour and color. it means the same just looks different that's all
