This is an important word and nobody has it right yet. What it means is: Trying too hard, unsubtle, and inauthentic.
Specifically that which is unsubtle or inauthentic in its way of trying to elicit a certain response from a viewer, listener, audience, etc. Celine Dion is cheesy because her lyrics, timbre, key changes, and swelling orchestral accompaniment telegraph 'i want you to be moved' instead of moving you.

The excessive showing off suggests he's compensating for what he does not have--i.e., he's actually poor, insecure, or short with an inferiority complex. Cliches are often cheesy because they are an obvious and artless way of making a point.

Sentimental and/or dramatic, yet superficial and unconvincing.

The word cheesy is often defined simply as "sentimental", but there is a key distinction between the two. A situation is cheesy when the characters, their motives, and/or their emotions are not believable. It is a sentimental moment (it could be extremely sad or happy), but there is a weak connection to the characters or their situation, thus making it cheesy.

Many people confuse the two, and it is a matter of opinion to a certain degree, but things can be sentimental, emotional, or dramatic without being cheesy.
