Can 'I'm as awesome as a possum' be a hyperbole?

Answer 1

First, this example is a simile-- comparing two unlike things, using "like" or "as" to make the comparison. Hyperbole refers to exaggerating to make a rhetorical point, such as "She served enough food to feed an army." Yes, your example could possibly be considered hyperbole, but it might be seen more as a clever phrase or an attempt at bragging, rather than as hyperbole.
