A pilus (Latin; plural : pili) is a hairlike structure on the surface of a cell, especially Gram-negative bacteria, a protein appendage required for bacterial conjugation. Pili connect the bacterium to another of its species and build a bridge between the cytoplasm of either cell. That enables the transfer of plasmids between the bacteria. An exchanged plasmid can add new functions to a bacterium, e.g., an antibiotic resistance.

Sometimes called a sex pilus (plural: sex pili). Up to ten of these structures can exist on the bacteria. Some bacterial viruses or bacteriphages attach to receptors on sex pili at the start of their reproductive cycle.

Despite the name "sex pilus", this has nothing to do with sexual reproduction or mating, nor is it the bacterial equivalent of a penis; such misnomers are used quite frequently in describing the process, and while may prove useful in understanding underlying concepts are misleading nonetheless.

A pilus is typically 9 to 10 nm in diameter. The sex pilus allows for the transfer of bacterial DNA from the bacteria with the pilus (donor) to the recipient bacteria. Through this mechanism of genetic transformation, advantageous genetic traits can be disseminated amongst a population of bacteria. Not all bacteria have the ability to create sex pili, however sex pili can form between bacteria of different species.

It is an extension of the cytoplasm and used for attachment to surfaces (and is then called a fimbrium) and conjugation with another cell of the same species.

Basically... a bacteria's dick.

Mili Pili is literally the Spanish abreviation of the female names Milagros and Pilar (especially argentinean spanish). It is used in a despective and derogatory way to refer to millenial teens who tend to have an extremely clumsy and naïve point of view about different topics on life, or whose lives evolve around silly and unrelevant things, such as wearing brand clothing or being the most popular girl at school. In all, it's a way to call a girl 'stupid'.
