mouth full of vaseline

When one speaks to you with a lisp and you cannot decipher a word that they say. Or when a person spits uncontrollably and has a lisp. It is permissible to yell "vaseline" with a lisp and cut one of these lispers off.

Man, that guy with a lisp was talkin with a mouth full of vaseline. What the hell was he talking about?

wavy-mouth

Da drawn-for-comedic-effect "squiggly-lips-line" facial expression dat a cartoonist employs to indicate a confused, shocked, or distressed mindset of da character displaying said weird look.

Sarge: Look at all these awful news-items in the newspaper --- fire, floods, famine, you name it! I wish I could hear even one little piece of actual GOOD news for a change!
Zero (in naive cheerfulness): My sore toe is better!
Sarge: (glances up at Zero with his classic "wavy-mouth" expression)
