An emoticon generally meant to look like a face with a tongue hanging out. like other emoticons/smileys, it's frequently used in
IM conversations, forum posts text messages, etc., especially by younger people. It usually signifies one of the following:
1. Somewhat sheepish (but good-humored) acknowledgment of (usually one's own) silliness, foolishness, absentmindedness, or ineptness. While often used to reflect one's own
state, it is also used in reference to others or situations.
2. Mild disgust, in other words, a stand-in for "ew" "
yuck". (More profound revulsion can be expressed with "XP", which is similarly meant to depict a hanging tongue, but adds
eyes squinted shut or nearly shut)
3. Tongue sticking out tauntingly. (Less
common. As
said earlier, :P is usually is interpreted as a tongue *hanging* out, not protruding straight forward)
This emoticon is a less literal depiction of expression than some other emoticons. For instance, someone who says in an
IM conversation "I totally flunked the
history test today :P" would not be likely to actually let his or her tongue actually loll out thus if the same conversation was held face-to-face. It probably has its roots in
long standing cartoon practice of showing stupid/knocked-out/dazed people with their tongues limply hanging out like a
dog's tongue on a hot
day.
The P is often capitalized, but not always. Additionally, there are variants forms like :-P, =P, :b, :-b, :-Þ, :Þ, etc.
