CREEP

Although his proper first name is not listed in any of the credits, Dustin Hoffman's character Babe does speak his full given name once: during police questioning after the murder of his brother, he is asked his name, and shouts out "Thomas Babington Levy". 

He also quickly identifies himself as "Tom Levy" when desperately trying to buzz into his neighbor's apartment building after being chased, ultimately having to identify himself as "The Creep", since no one there knows him by his real name.

A RADICALLY CONDENSED HISTORY OF POSTINDUSTRIAL LIFE

by David Foster Wallace

When they were introduced, he made a witticism, hoping to be liked. She laughed extremely hard, hoping to be liked. Then each drove home alone, staring straight ahead, with the very same twist to their faces. 

The man who’d introduced them didn’t much like either of them, though he acted as if he did, anxious as he was to preserve good relations at all times. One never knew, after all, now did one now did one now did one.

Author Robert Barker contrasted Eighth Grade to earlier coming-of-age films such as Fast Times at Ridgemont High (1982) and Mean Girls (2004). 

Rather than work through cliques, Barker wrote, Kayla and others are on “a digital war of All against All, preening, pretending, and pontificating as much to themselves as to an anonymous audience”. 

Barker also saw the sexting between characters as representing their obliviousness to lost innocence.
