Imposters that attend cultural events solely for free food and alcohol. These free loaders manipulate vulnerable clueless hosts for invitations. They strategize through lies and dishonest intentions. The master manipulators pretend to care about your customs. They will go as far as to wear a Yamaka on top of there nappy afros. They will fake laugh at jokes as-well pretend to adore and tolerate your nasty untrained pets. They influence children to partake in unhealthy immature practices such as drinking alcohol.

They are lowly members of society and remember to not invite them into your home!
