Cheesy is an important word and nobody has it right yet. What it means is: Trying too hard, unsubtle, and inauthentic.
it's a unsubtle way of trying to elicit a certain response from someone or impress them by simply trying to hard to be cool. But what does cheese have to do with it, cause what we know about cheese is that the longer you store it the better it gets.. so even if you go over the top to store a Gauda for 12 years, it will still be good, actually it will taste even better and like a cheese fondue can never be to cheesy, or if you order x-tra cheese on your burger thats not cheesy either.. but when you say that someone stole all the stars in the sky and placed them in your eyes, then you are cheesy... so i guess the only thing you can compare it with is a cheese ( a person) who is actually good, but because he or she or it is trying to hard to get approval and be liked.. Then its like a good cheese in bad wrapper. and dude that is cheesy.
