How do you say your gross in japanese?

Answer 1

Assuming the user was fairly young, one would say 君ってキモイ (kimitte kimoi) or even just キモイ (kimoi) to mean 'you're gross'. Teenagers would even commonly say just キモ (kimo).

キモイ (kimoi) is the shortened form of 気持ち悪い (kimochiwarui) which means to feel sick. Kimoi is considered to be slang and is commonly used by teenagers in Japan to refer to something as 'gross'.
