Which poetic form consists of five lines with a specific rhyme scheme?

The poetic form that consists of five lines with a specific rhyme scheme is the limerick. Limericks are known for their distinct pattern of rhythm and rhyme, typically following an AABBA scheme. The first, second, and fifth lines usually contain three metrical feet, while the third and fourth lines have two metrical feet. This unique structure, combined with its often humorous or whimsical content, makes limericks easily recognizable and fun to read. The other forms listed do not fit this description: haikus are three-line poems with a specific syllable pattern, sonnets are 14-line poems often with more complex rhyme schemes, and couplets consist of just two lines that usually rhyme.
