McKayla Maroney Is REALLY Not Impressed

No one can ever accuse Olympic gymnast McKayla Maroney of not having a sense of humor ... because even she is jumping on the McKayla Is Not Impressed bandwagon.

For those who don't know ... a photo of a scowling McKayla (see below) was taken after she won the silver medal in the vault competition. It spawned a Photoshop movement of putting McKayla in various places ... looking unimpressed (as best evidenced by the site mckaylaisnotimpressed.tumblr.com).

McKayla got in on the gag herself today, posting a photo of herself recreating the face with fellow Fab Fivers Kyla Ross and Aly Raisman.

We give it a perfect score.
