A person who wile preparing a libation that requires muddling; muddles in an overkill fashion, to the point where "bits" from every sip end up in your mouth.
Wow, Alice really smashed the mint in my mojito to smithereens. What a muddler fucker!
The dirtiest, filthiest, most sexually repulsive act. It varies with each definition, all the constant response should be "don't be filthy". It can be described as a simple ATM or a Brown ATM with JAM, it could be any variation of a dirty sanchez, a dirty bucharian, a cleaveland steamer. But generally the worst thing one can think of.
Girl: I thought it was strange when he asked me for a french muddler...like he knew me or something.
A:What's a french muddler?
B:Don't be nasty yo.
When a woman tries to impregnate herself by scavenging cum from a used condom unbeknownst to the male in an attempt to baby trap him. Especially in the form of using a muddler to force the sperm all up into her vaginal canal, even though a baster would have been much more efficient, but she's clearly just a bartender and can't for shit.
As a man of your prowess, watch out for that bartender, she's sexy AF but also a gold diggingcum muddler!
