heaps

bare
Means loads of, or a lot of something. It also works like 'really' or 'very' to crank up whatever you're saying.
There were bare people at the party last night, it was bare jokes.
hella
Means 'really', 'super', or 'a ton of'. It's classic Bay Area and NorCal slang, and you can put it in front of an adjective or a noun.
That concert was hella fun, but there were hella people in line.
wicked
In New England, especially around Boston, wicked just means "really" or "super." You put it in front of an adjective to crank it up, and it has nothing to do with being evil.
That lobster roll was wicked good, we have to come back here.
