Mountain with Wings

Slang for when someone tries to justify a decision they made by giving a superficial meaning to their actions that doesn't make any sense, and/or is typically so transparent it's obvious to see that there was no thought put into said decision.

Person 1: Dude, did you see the new rims on Alex's honda civic? He said he gets like +50 horsepower from them!
Person 2: (laughs hysterically) All he did was waste $800 because he wants to be noticed by someone for once in his life. All those rims are is a mountain with wings.
