Haiku poem

A haiku poem is a five syllable line, followed by a seven syllable line and then a five syllable line.

An SMS haiku poem would be;
b4 i c u
br8 me if  u 1 2
jus c me l8r
An SMS haiku poem would work best for IM and SMS on your phone as these are both informal ways of writing to someone and good English is not necessary as you can use slang and text talk, where as with email it should be a formal letter and an SMS haiku poem wouldnt work as it should be done in text talk and can include slang.
