wrinkle your birthday suit

Cramping one's style.

The loss of or inability to get an erection.

You sure riding the moped tonight won't wrinkle your birthday suit?

Your fat cousin really wrinkles my birthday suit.

riding the moped

Hooking up with a fat, ugly or otherwise embarrassing person.

Doing anything that is outright lame and pathetic and would be humiliating if your friends saw you doing it.

You were the wingman last night so tonight I'll be riding the moped.
