Practice Kiss

The Practice Kiss is what happens when two people who are not in a relationship decide to try kissing each other, ostensibly for non-romantic reasons. Commonly, this is shown to happen between characters who are teenagers, with at least one of them being inexperienced in kissing or romance in general.

If neither party has ever experienced a First Kiss and are suffering Angst about the possibility of making fools of themselves while doing so, one may suggest a Practice Kiss so that they can more easily impress their current or future significant others. Alternatively, they may just want to see what kissing feels like. While it may not be the kissers' original intent, doing so may be the spark that causes one or both of the characters to develop feelings for the other. If one of the kissers does have previous experience, the other will usually be shown to be quite flustered after the fact.

The Practice Kiss can also be used as a ploy when one character is secretly in love with the other, but just Cannot Spit It Out. This may be done as a means to make the other character notice them romantically, or simply so that they may experience their True Love's Kiss at least once before letting go of the object of their affection. While this provides an easy source of sexual tension between the pair, the plan can backfire if they are caught in the act... especially if the person being kissed is already in another relationship.

If both participants are of the same sex, it can also be a prime source of Ho Yay. This can be done solely for the benefit of the show's fans, or to serve as the moment one of the characters starts to realize that they are gay.

Note that this is distinct from the Test Kiss, which is when potential lovers try kissing each other to see if there is a romantic spark between them. They can overlap, however, as what may be a Practice Kiss to one of the characters may secretly be a Test Kiss for another.

Compare Kissing Warm Up, where a character practices by kissing an inanimate object.
