A Liam usually licks up a girl and then ignores her for the rest of his life. If you meet a Liam, run as fast as possible since he's bisexual and will lick your arse.
Liams can sometimes be funny, but are mostly irritating. They seem to care but in reality, they suck tits.
Liams can usually be spotted at gyms trying to impress a girl or at a pub with the boyos.
Look at Liam. He's such a try hard.
liam is a guy who likes the screwdriver, but has a thing for a girl called libby
'bruh that guys fisting a boy'
'hes such a liam'
An amazing, unique, and fun to hang out with person. He's a fun-loving, extroverted person that you can always feel comfortable sharing whatever's on your mind to, and the sheer fact of his existence lightens up whatever room he's in, like a candle, if it had fluffy hair and puppy-dog eyes. Liam is always there for you when you need to laugh with, to love with, or even just to live with.
omg, i know ive already talked about him twice today, but can i tell you something about liam again?
The people referred to as "Liams" will often be unable to communicate in the traditional sense, often resorting to spewing nonsense in a bid for attention. This will most likely be looked down upon by others, resulting in a pseudo-relationship in which people are forced to endure Liams rather than enjoy their company. "Liam" is thought to refer to Liam Gallagher, who no one really likes, but that's just a theory, a game theory.
"I'm so bored of jim, he's acting like a liam."
"That guy seems like one of the Liams, similar to Liam Gallagher, and thus I'm referring to him as such."
