Dictionaries define 肉麻 as nauseating; sickening; disgusting. But I don't think those are accurate because those words are showing disproval while 肉麻 could show approval depending on how you use it. The word is being used when somebody says something overly sweet. E.g.
A: 我太喜欢你了！ 我愿意天天和你在一起！
B: 好肉麻啊。
This might be a question for the ELL site. But I don't know how to describe the word precisely in English, so I might just ask here. Any suggestions? Thanks!
Consider: gushy.
Google defines it as:
gushy /ˈɡʌʃi/
adjective
excessively effusive.
and gives the example:
"her gushy manner"
91dub also has the show《牛仔裤的夏天》subtitled with the sentence:
Especially when they started being all gushy.
尤其是在很肉麻的时候.
Cheesy,前几天在一个英文广播上听到的。广播里的外国主播对于cheesy使用场景的描述是:we often use it to talk about overly sentimental songs,movies or people who sing those songs or acting those movies.
In the given context, I'd plump for:
B: Errrh! Gross!
but this will never "show approval."
Maybe, if no disapproval is intended, which I assumed:
B: You're making me blush!
