You know that moment, when you can't remember someone's name - but deep down, you know it ... ?
What about the word that won't come to the tip of your tongue ...

Well, apparently, there's a word for it ... now what was it? ...

Definition: inability to remember a word or put your finger on the right word.

Wikipedia:
Lethologica is a psychological disorder that inhibits an individual's ability to articulate his or her thoughts by temporarily forgetting key words, phrases or names in conversation.

Lethologica was first identified as a serious, debilitating disorder by Swiss psychiatrist Carl Jung in 1913 in his Wandlungen und Symbole der Libido (The Psychology of the Unconscious).

Lethologica's severity amongst sufferers is dependent upon a variety of factors including stress, physical fitness, social interaction and base memory capacity. As such it can be classified as a lifestyle disease which is also affected by individual personality traits. These factors have been shown to affect the temporal lobe which in turn causes the sporadic functioning of episodic and semantic memory capacities.

Sorry but no effective treatments for the disorder exist !

Hmmm ... interesting ...
