Fillerphile: Any person that, when speaking or participating in a conversation they clearly know nothing about, will insert numerous pointless filler words in an attempt to make it sound more interesting.
This trait is common among the 20-something generation (the GIMME / Failure to launch generation) and office retards that are just lucky to have jobs because they know someone at the company.
Offenders typically touch their their chins when talking and nod a lot giving the illusion they understand.
I actually do really know that I am completely 1/2 American.
Fillerphile is not used in conversation. It's a defining term.
