(Lilleyman Moment) The moment in a conversation where all members are laughing at a mutual joke etc. Then one member feels the need to input on the conversation. Usually resulting in an awkward silence and embarrassment for the certain person.

James: "John, can fit your fist in your mouth."
Rebecca: "Wow, I can't!"

*group laughs at James' attempt*
Alex: "I know where you'd like to put your fist Joe, up John's arse."

*silence*

lm 

Acronym for Lawn Mower, referring to a very slow, four wheeled motor vehicle with a broken or distastefully modified muffler, causing it to sound like a Lawn Mower. The operators of these vehicles are generally men between the ages of 16 and 25 who enjoy making noise with their mufflers by driving around using the lowest possible gear. This often results in attempts at races with high performance automobiles and motorcycles, obviously ending shame.

Rider of Suzuki GSX-R1000 high performance motorcycle:
"Look at this guy in the Honda Civic with the fart can, is he trying to race me? What an LM!"

"That LM is all show and no go."
