Basic surf lingo questions

ok guys i have surfed for about 5 years now, i am 21 and i love surfing.
i just have some questions about surfing lingo i never hung out with surfers so i do not know too much about all the lingo.
first what is overhead? i assume its the size of the wave but if its triple overhead how is that justified? is it compared to your size?
also what is face? is it just the smooth part of the wave before it breaks into whitewash?
thanks guys and sorry if this is not the right place to post this.
