It was none other than IFP leader Mangosuthu Buthelezi who used his acerbic sense of humour and coined the term "crosstitutes".
Buthelezi was referring to the politicians who ditched their parties to join others without losing their seats in the legislatures, accusing them of being self-serving men and women who were prepared "to peddle their political asses" for positions.
When floor-crossing was introduced in 2002, Buthelezi was not happy with the idea, more so because during the two floor-crossing windows after the law was passed, the ANC benefited the most - increasing its parliamentary seats from 252 to 279.
The IFP lost six "crosstitutes", reducing its seats in parliament to 28.
The UDM, which unsuccessfully challenged the new law in the constitutional court, lost five "crosstitutes", remaining with nine seats.
The ID was formed after its founder, Patricia de Lille, ditched the PAC and gained seven "crosstitutes" in the process.
The DA benefited the second most after embracing 12 "crosstitutes" to increase its parliamentary tally to 50 seats.
