What's a 'Pantun'?

The answer from Wikipedia.org:

The Pantun is a Malay poetic form. The pantun originated as an oral literary form of expression traditionally used among the Malays. Pantun had been in its current form since 15th century at the latest, based on Malay manuscripts written within this period.

In its most basic form the pantun consists of even-numbered lines based on an abab rhyming scheme, with the shortest pantun consisting of two lines, and it can go up to 16 lines, but 4 is more likely. A pantun is traditionally recited according to a fixed rhythym and as a rule of thumb, in order not to deviate from the rhythym, every line should contain between eight and 12 syllables.

Pantuns are written in quatrains, generally following an abab rhyme scheme. The second and fourth lines of each stanza become the first and third lines of the following stanza. Finally, the first and third lines of the first stanza become the second and fourth lines of the last stanza, usually in reverse order so that the first and last lines of the poem are identical.

Quatrains: A quatrain is a poem or a stanza within a poem that consists of four lines. It is the most common of all stanza forms in European poetry. In its narrow meaning, the term is restricted to a complete poem consisting of only four lines. In its broader sense, it includes any one of many four-verse stanza form.

Rhyme Scheme: A rhyme scheme is the pattern of rhyming lines in a poem or in lyrics for music. It is usually referred to by using letters to indicate which lines rhyme. For example "abab" indicates a four-line stanza in which the first and third lines rhyme, as do the second and fourth.

Stanza: In poetry, a 'stanza' is a unit within a larger poem. (The term means "room" in Italian.) In modern poetry, the term is often equivalent with strophe; in popular vocal music, a stanza is typically referred to as a "verse" (as distinct from the refrain, or "chorus").
