LeBroning around 

1) unclutch
2) inability to close or win
3) ability to disappear in the face of adversity

Inspired by LeBron James' uninspired play during the playoffs and in the 4th quarter.

Examples:

"Hey Matt, will you stop LeBroning around and just get that girl's number already."

"Where did he go in the 4th quarter? -- Oh, he must have been LeBroning around."

"I couldn't cut it as a Navy Seal, I just LeBroned around too much."

"Jim Kelly knows all about LeBroning around."

In the huddle during Superbowl XXXIX:

McNabb: "Ok guys, the play is...uh..the ..plaaa.. isss.."
TO: "Donovan, my leg is still broken, quit LeBroning around."

LaBronica 

An eight day period from July 1-July 8 similar to Hanukkah during which NBA teams shower gifts on free agents in an attempt to get them to sign with their team.

On the second day of LaBronica the Bulls took D-Wade and Bosh out to dinner, while LaBron was being wined and dined in New York.

leBroning 

1: to prove ones value ostentatiously

2: to only work ones hardest or give ones best effort when one wants to prove a point to someone. On other occasions minimal necessary effort is be given.

Steve was lebroning hardcore yesterday after George said his best work was average at best.

LeBroning 

LeBron James the overrated NBA player who tosses powder in the air before every game. LeBroning is the act of powdering yourself. In most cases it involves powdering your butt/butt hole by tossing powder up there cause your anus feels inside out, and there is no easy way of getting powder up there. Also, it helps to eliminate the burning between your cheeks and thighs after a workout without compression shorts.

Excuse me I have to go LeBron my asshole

I just Lebroned my butt, and it feels so much better.

Please don't come in cause I am LeBroning myself, and it's not a pretty sight.
