This comic is based on wordplay, which was lost in translation. Ucchi's 'gross' catchphrase is originally 'kimoi', a contraction of 'kimochi warui' (literally 'feels bad'). 'Feels good' is 'kimochi ii'. So it seems kind of random in English but the reason Tomoko said she can only say that is because it's a direct inversion of what she normally says in Japanese.
